The LP2985-N low noise linear regulator delivers up
to 150-mA output current and only requires 300-mV
dropout voltage of input to output. Using an optimized
VIP (Vertically Integrated PNP) process, the LP2985N delivers unequaled performance for all batterypowered designs. The LP2985-N device provides 1%
tolerance precision output voltage with only 75 µA
quiescent current at 1 mA load and 850 µA at 150
mA load. By adding a 10-nF bypass capacitor, the
output noise can be reduced to 30 µV
in a 30-kHz
RMS
bandwidth.
The LP2985-N is designed to work with a ceramic
output capacitor with equivalent series resistance
(ESR) as low as 5 mΩ. The devices are available
with fixed output voltage from 2.5 V to 6.1 V. Contact
Texas Instrument Sales for specific voltage option
needs.
The smallest SOT-23 and DSBGA packages are
available for absolute minimum board space.

8 Detailed Description
8.1 Overview
The LP2985-N family of fixed-output, ultra-low-dropout and low-noise regulators offers exceptional, cost-effective
performance for battery-powered applications. Available in output voltages from 2.5 V to 5 V, the family has an
output tolerance of 1% for the A version (1.5% for the non-A version) and is capable of delivering 150-mA
continuous load current. Standard regulator features, such as overcurrent and overtemperature protection, are
also included.
Using an optimized Vertically Integrated PNP (VIP) process, the LP2985-N contains several features to facilitate
battery powered designs:
• Multiple voltage options
• Low dropout voltage, typical dropout of 300 mV at 150 mA load current and 7 mV at 1 mA load.
• Low quiescent current and low ground current, typically 850-μA at 150 mA load, and 75-μA at 1-mA load.
• A shutdown feature is available, allowing the regulator to consume only 0.01-uA typically when the ON/OFF
pin is pulled low.
• Over Temperature Protection and Over Current Protection circuitry is designed to safeguard the device during
unexpected conditions
• Enhanced Stability: The LP2985-N is stable with output capacitor ESR as low as 5-mΩ, which allows the use
of ceramic capacitors on the output.
• Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30 µV
use of a 10-nF bypass capacitor.

8.2 Functional Block Diagram
8.3 Feature Description
8.3.1 Multiple Voltage Options
In order to meet different application’s requirement, the LP2985-N family provide multiple fixed output options
from 2.5 V to 6.1 V. Please consult factory for custom voltages.
8.3.2 Output Voltage Accuracy
Output voltage accuracy specifies minimum and maximum output voltage error, relative to the expected nominal
output voltage stated as a percent. This accuracy error includes the errors introduced by the internal reference
and the load and line regulation across the full range of rated load and line operating conditions over
temperature, unless otherwise specified by the Electrical Characteristics. Output voltage accuracy also accounts
for all variations between manufacturing lots.

Feature Description (continued)
8.3.3 Ultra-Low Dropout Voltage
Generally speaking, the dropout voltage often refers to the voltage difference between the input and output
voltage (VDO= VIN– V
characterized by the classic R
nominal programmed output voltage at which the output voltage is expected to remain within its accuracy
boundary. If the input falls below this VDOlimit (VIN< V
follow the input voltage.
8.3.4 Low Ground Current
LP2985-N uses a vertical PNP process which allows for quiescent currents that are considerably lower than
those associated with traditional lateral PNP regulators, typically 850 μA at150 mA load, and 75 μA at 1-mA load.
8.3.5 Sleep Mode
When pull ON/OFF pin to low level, LP2985-N will enter sleep mode, and less than 2-μA quiescent current is
consumed. This function is designed for the application which needs a sleep mode to effectively enhance battery
life cycle.
8.3.6 Internal Protection Circuitry
8.3.6.1 Short Circuit Protection (Current Limit)
The internal current limit circuit is used to protect the LDO against high-load current faults or shorting events. The
LDO is not designed to operate in a steady-state current limit. During a current-limit event, the LDO sources
constant current. Therefore, the output voltage falls when load impedance decreases. Note also that if a current
limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO, resulting
in a thermal shutdown of the output.
A fold back feature limits the short-circuit current to protect the regulator from damage under all load conditions.
If V
is forced below 0 V before EN goes high and the load current required exceeds the fold back current limit,

of the FET. VDOindirectly specifies a minimum input voltage above the

+ VDO), then the output voltage decreases in order to
OUT
8.3.6.2 Thermal Protection
The LP2985-N contains a thermal shutdown protection circuit to turn off the output current when excessive heat
is dissipated in the LDO. The thermal time-constant of the semiconductor die is fairly short, and thus the output
cycles on and off at a high rate when thermal shutdown is reached until the power dissipation is reduced.
The internal protection circuitry of the LP2985-N is designed to protect against thermal overload conditions. The
circuitry is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown
degrades its reliability.
8.3.7 Enhanced Stability
The LP2985-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows the
regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low as
5 mΩ. For output capacitor requirement, please refer to Output Capacitor.
8.3.8 Low Noise
The LP2985-N includes a low-noise reference ensuring minimal noise during operation because the internal
reference is normally the dominant term in noise analysis. Further noise reduction can be achieved by adding an
external bypass bapacitor between the BYPASS pin and the GND pin.

8.4.2 Operation With ON/OFF Control
If the voltage on the ON/OFF pin is less than 0.15 V, the device is disabled, and in this state shutdown current
does not exceed 2 μA. Raising ON/OFF above 1.6 V initiates the start-up sequence of the device.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The LP2985-N is a linear voltage regulator operating from 2.5 V to 16 V on the input and regulates voltages
between 2.5 V to 6.1 V with 1% accuracy and 150-mA maximum output current. Efficiency is defined by the ratio
of output voltage to input voltage because the LP2985-N is a linear voltage regulator. To achieve high efficiency,
the dropout voltage (VIN– V
Successfully implementing an LDO in an application depends on the application requirements. If the
requirements are simply input voltage and output voltage, compliance specifications (such as internal power
dissipation or stability) must be verified to ensure a solid design. If timing, start-up, noise, power supply rejection
ratio (PSRR), or any other transient specification is required, then the design becomes more challenging.

9.2.2 Detailed Design Procedure
At 150-mA loading, the dropout of the LP2985-N has 575-mV maximum dropout over temperature, thus an 1000mV headroom is sufficient for operation over both input and output voltage accuracy. The efficiency of the
LP2985-N in this configuration is V
/ VIN= 76.7%. To achieve the smallest form factor, the SOT-23 package is
OUT
selected.
Input and output capacitors are selected in accordance with the Capacitor Characteristics section. Ceramic
capacitances of 1 μF for the input and one 2.2-μF capacitor for the output are selected. With an efficiency of
76.7% and a 150 mA maximum load, the internal power dissipation is 150-mW, which corresponds to a 26°C
junction temperature rise for the SOT-23 package. With an 85°C maximum ambient temperature, the junction
temperature is at 111°C. To minimize noise, a bypass capacitance (C
) of 0.01 μF is selected.
BYPASS
9.2.2.1 External Capacitors
Like any low-dropout regulator, the LP2985-N requires external capacitors for regulator stability. These
capacitors must be correctly selected for good performance.
9.2.2.1.1 Input Capacitor
An input capacitor whose capacitance is ≥ 1 µF is required between the LP2985-N input and ground (the amount
of capacitance may be increased without limit).
This capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean
analog ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input.
NOTE
Tantalum capacitors can suffer catastrophic failure due to surge current when connected
to a low-impedance source of power (like a battery or very large capacitor). If a Tantalum
capacitor is used at the input, it must be ensured by the manufacturer to have a surge
current rating sufficient for the application.
There are no requirements for ESR on the input capacitor, but tolerance and temperature coefficient must be
considered when selecting the capacitor to ensure the capacitance will be ≥ 1 µF over the entire operating
temperature range.
9.2.2.1.2 Output Capacitor
The LP2985-N is designed specifically to work with ceramic output capacitors, utilizing circuitry which allows the
regulator to be stable across the entire range of output current with an output capacitor whose ESR is as low as
5 mΩ. It may also be possible to use Tantalum or film capacitors at the output, but these are not as attractive for
reasons of size and cost (see Capacitor Characteristics).
The output capacitor must meet the requirement for minimum amount of capacitance and also have an ESR
value which is within the stable range. Curves are provided which show the stable ESR range as a function of
load current (see Figure 22).

NOTE
The output capacitor must maintain its ESR within the stable region over the full operating
temperature range of the application to assure stability.
The LP2985-N requires a minimum of 2.2 µF on the output (output capacitor size can be increased without limit).
It is important to remember that capacitor tolerance and variation with temperature must be taken into
consideration when selecting an output capacitor so that the minimum required amount of output capacitance is
provided over the full operating temperature range. It should be noted that ceramic capacitors can exhibit large
changes in capacitance with temperature (see Capacitor Characteristics). The output capacitor must be located
not more than 1 cm from the output pin and returned to a clean analog ground.
9.2.2.1.3 Noise Bypass Capacitor
Connecting a 10 nF capacitor to the BYPASS pin significantly reduces noise on the regulator output. It should be
noted that the capacitor is connected directly to a high-impedance circuit in the bandgap reference.
Because this circuit has only a few microamperes flowing in it, any significant loading on this node will cause a
change in the regulated output voltage. For this reason, DC leakage current through the noise bypass capacitor
must never exceed 100 nA, and should be kept as low as possible for best output voltage accuracy.
The types of capacitors best suited for the noise bypass capacitor are ceramic and film. High-quality ceramic
capacitors with either NPO or COG dielectric typically have very low leakage. 10 nF polypropolene and
polycarbonate film capacitors are available in small surface-mount packages and typically have extremely low
leakage current.
9.2.2.2 Capacitor Characteristics
The LP2985-N was designed to work with ceramic capacitors on the output to take advantage of the benefits
they offer: for capacitance values in the 2.2 µF to 4.7 µF range, ceramics are the least expensive and also have
the lowest ESR values (which makes them best for eliminating high-frequency noise). The ESR of a typical 2.2
µF ceramic capacitor is in the range of 10 mΩ to 20 mΩ, which easily meets the ESR limits required for stability
by the LP2985-N.
One disadvantage of ceramic capacitors is that their capacitance can vary with temperature. Most large value
ceramic capacitors (≥ 2.2 µF) are manufactured with the Z5U or Y5V temperature characteristic, which results in
the capacitance dropping by more than 50% as the temperature goes from 25°C to 85°C.
This could cause problems if a 2.2 µF capacitor were used on the output since it will drop down to approximately
1 µF at high ambient temperatures (which could cause the LM2985 to oscillate). If Z5U or Y5V capacitors are
used on the output, a minimum capacitance value of 4.7 µF must be observed.

A better choice for temperature coefficient in ceramic capacitors is X7R, which holds the capacitance within
±15%. Unfortunately, the larger values of capacitance are not offered by all manufacturers in the X7R dielectric.
Tantalum capacitors are less desirable than ceramics for use as output capacitors because they are more
expensive when comparing equivalent capacitance and voltage ratings in the 1 µF to 4.7 µF range.
Another important consideration is that Tantalum capacitors have higher ESR values than equivalent size
ceramics. This means that while it may be possible to find a Tantalum capacitor with an ESR value within the
stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic
capacitor with the same ESR value.
It should also be noted that the ESR of a typical Tantalum will increase about 2:1 as the temperature goes from
25°C down to −40°C, so some guard band must be allowed.
9.2.2.3 ON/OFF Input Operation
The LP2985-N is shut off by driving the ON/OFF input low, and turned on by pulling it high. If this feature is not to
be used, the ON/OFF input should be tied to VINto keep the regulator output on at all times.
To assure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and
below the specified turn-on/turn-off voltage thresholds listed in the Electrical Characteristics section under
V
. To prevent mis-operation, the turn-on (and turn-off) voltage signals applied to the ON/OFF input must
ON/OFF
have a slew rate which is ≥ 40 mV/µs.
CAUTION
The regulator output voltage cannot be ensured if a slow-moving AC (or DC) signal is
applied that is in the range between the specified turn-on and turn-off voltages listed
under the electrical specification V
(see Electrical Characteristics).
ON/OFF
9.2.2.4 Reverse Input-Output Voltage
The PNP power transistor used as the pass element in the LP2985-N has an inherent diode connected between
the regulator output and input. During normal operation (where the input voltage is higher than the output) this
diode is reverse-biased).

However, if the output is pulled above the input, this diode will turn ON and current will flow into the regulator
output. In such cases, a parasitic SCR can latch which will allow a high current to flow into VIN(and out the
ground pin), which can damage the part.
In any application where the output may be pulled above the input, an external Schottky diode must be
connected from VINto V
(cathode on VIN, anode on V
OUT
), to limit the reverse voltage across the LP2985-N to
OUT
0.3 V (see Absolute Maximum Ratings).

10 Power Supply Recommendations
The LP2985-N is designed to operate from an input voltage supply range between VINof 2.5 V and 16 V.
(Recommended minimum VINis the greater of 3.1 V or V
OUT(max)
+ rated dropout voltage (max) for operating load
current.) The input voltage range provides adequate headroom in order for the device to have a regulated output.
This input supply must be well regulated. If the input supply is noisy, additional input capacitors with low ESR can
help to improve the output noise performance.
11 Layout
11.1 Layout Guidelines
For best overall performance, place all circuit components on the same side of the circuit board and as near as
practical to the respective LDO pin connections. Place ground return connections to the input and output
capacitor, and to the LDO ground pin as close to each other as possible, connected by a wide, component-side,
copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and
negatively affects system performance. This grounding and layout scheme minimizes inductive parasitics, and
thereby reduces load-current transients, minimizes noise, and increases circuit stability.
A ground reference plane is also recommended and is either embedded in the PCB itself or located on the
bottom side of the PCB opposite the components. This reference plane serves to assure accuracy of the output
voltage, shield noise, and behaves similar to a thermal plane to spread (or sink) heat from the LDO device. In
most applications, this ground plane is necessary to meet thermal requirements.
11.2 Layout Example
Figure 39. LP2985 SOT-23 Package Typical Layout
Figure 40. LP2985 DSBGA Package Typical Layout
11.3 DSBGA Mounting
The DSBGA package requires specific mounting techniques which are detailed in AN-1112 DSBGA Wafer Level
Chip Scale Package (SNVA009). Referring to the section Surface Mount Technology (SMT) Assembly
Considerations, it should be noted that the pad style which must be used with the 5-pin package is the NSMD
(non-solder mask defined) type.
For best results during assembly, alignment ordinals on the PC board may be used to facilitate placement of the
DSBGA device.

11.4 DSBGA Light Sensitivity
Exposing the DSBGA device to direct sunlight will cause misoperation of the device. Light sources such as
Halogen lamps can also affect electrical performance if brought near to the device.
The wavelengths which have the most detrimental effect are reds and infra-reds, which means that the
fluorescent lighting used inside most buildings has very little effect on performance. A DSBGA test board was
brought to within 1 cm of a fluorescent desk lamp and the effect on the regulated output voltage was negligible,
showing a deviation of less than 0.1% from nominal.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
