SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007

The TPS799xx family of low-dropout (LDO) low-power linear regulators offer excellent AC performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 40 µ A (typical) ground current. The TPS799xx is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield dropout voltage typically 100mV at 200mA output. The TPS799xx uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% over all load, line, process, and temperature variations. It is fully specified from TJ= – 40 ° C to +125 ° C and is offered in low profile ThinSOT23, Wafer Chip-Scale (WCSP), and 2mm × 2mm SON packages, ideal for wireless handsets and WLAN cards.

APPLICATIONS

• Cellular Phones

• Wireless LAN, Bluetooth

• VCOs, RF

• Handheld Organizers, PDAs

SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. EN can be connected to IN if not used.

Fixed voltage versions only; connecting an external capacitor to this pin bypasses noise low levels.

Adjustable version only; this pin is the input to the control loop error amplifier, and is used to set the output voltage of the device.

Output of the regulator. A small capacitor (total typical capacitance ≥ 2.0 µ F ceramic) is needed from this pin to ground to assure stability.

TPS799xx

SBVS056I – JANUARY 2005 – REVISED NOVEMBER 2007

APPLICATION INFORMATION

The TPS799xx family of LDO regulators combines the high performance required of many RF and precision analog applications with ultra-low current consumption. High PSRR is provided by a high gain, high bandwidth error loop with good supply rejection at very low headroom (V

– V

IN

). Fixed voltage

OUT

versions provide a noise reduction pin to bypass noise generated by the bandgap reference and to improve PSRR while a quick-start circuit fast-charges this capacitor at startup. The combination of high performance and low ground current also make the TPS799xx an excellent choice for portable applications. All versions have thermal and over-current protection and are fully specified from – 40 ° C to +125 ° C.

Figure 28 shows the basic circuit connections for

fixed voltage models. Figure 29 gives the connections for the adjustable output version (TPS79901). R R

Input and Output Capacitor Requirements

Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1 µ F to 1 µ F low ESR capacitor across the input supply near the regulator. This will counteract reactive input sources and improve transient response, noise rejection, and ripple rejection. A higher-value capacitor may be necessary if large, fast rise-time load transients are anticipated or the device is located several inches from the power source. If source impedance is not sufficiently low, a 0.1 µ F input capacitor may be necessary to ensure stability.

The TPS799xx is designed to be stable with standard ceramic capacitors of values 2.2 µ F or larger. X5R and X7R type capacitors are best as they have minimal variation in value and ESR over temperature. Maximum ESR should be < 1.0 Ω . space

Feedback Capacitor Requirements (TPS79901 only)

The feedback capacitor, C required for stability. For a parallel combination of R and R

equal to 250k Ω , any value from 3pF to 1nF

2

can be used. Fixed voltage versions have an internal 30pF feedback capacitor which is quick-charged at start-up. The adjustable version does not have this quick-charge circuit, so values below 5pF should be used to ensure fast startup; values above 47pF can be used to implement an output voltage soft-start. Larger value capacitors also improve noise slightly. The TPS79901 is stable in unity-gain configuration (OUT tied to FB) without C

Output Noise

significantly to noise. Instead, noise is dominated by the output resistor divider and the error amplifier input. To minimize noise in a given application, use a

0.01 µ F noise reduction capacitor; for the adjustable version, smaller value resistors in the output resistor divider reduce noise. A parallel combination that gives 2 µ A of divider current will have the same noise performance as a fixed voltage version. To further optimize noise, equivalent series resistance of the output capacitor can be set to approximately 0.2 Ω . This configuration maximizes phase margin in the control loop, reducing total output noise by up to 10%.

The TPS79901 adjustable version does not have the noise-reduction pin available, so ultra-low noise operation is not possible. Noise can be minimized according to the above recommendations.

Board Layout Recommendations to Improve

(1)

Startup

Fixed voltage versions of the TPS799xx use a quick-start circuit to fast-charge the noise reduction capacitor, C Diagrams, Figure 1 ). This allows the combination of very low output noise and fast start-up times. The NR pin is high impedance so a low leakage C must be used; most ceramic capacitors are appropriate in this configuration.

Note that for fastest startup, V first, then the enable pin (EN) driven high. If EN is

To improve ac performance such as PSRR, output noise, and transient response, it is recommended that the board be designed with separate ground planes for V

and V

IN

, with each ground plane connected

OUT

only at the GND pin of the device. In addition, the ground connection for the bypass capacitor should connect directly to the GND pin of the device.

Internal Current Limit

The TPS799xx internal current limit helps protect the regulator during fault conditions. During current limit, the output will source a fixed amount of current that is largely independent of output voltage. For reliable operation, the device should not be operated in current limit for extended periods of time.

The PMOS pass element in the TPS799xx has a built-in body diode that conducts current when the voltage at OUT exceeds the voltage at IN. This current is not limited, so if extended reverse voltage operation is anticipated, external limiting may be appropriate.

Shutdown

The enable pin (EN) is active high and is compatible with standard and low voltage TTL-CMOS levels. When shutdown capability is not required, EN can be connected to IN.

Dropout Voltage

The TPS799xx uses a PMOS pass transistor to achieve low dropout. When (V the dropout voltage (V

), the PMOS pass device is

in its linear region of operation and the input-to-output resistance is the R

DS, ON

section. The quick-start switch is closed for approximately 135 µ s. To ensure that C

is fully

NR

charged during the quick-start time, a 0.01 µ F or smaller capacitor should be used.

Transient Response

As with any regulator, increasing the size of the output capacitor will reduce over/undershoot magnitude but increase duration of the transient response. In the adjustable version, adding C between OUT and FB will improve stability and transient response. The transient response of the TPS799xx is enhanced by an active pull-down that engages when the output overshoots by approximately 5% or more when the device is enabled. When enabled, the pull-down device behaves like a 350 Ω resistor to ground.

Under-Voltage Lock-Out (UVLO)

The TPS799xx utilizes an under-voltage lock-out circuit to keep the output shut off until internal circuitry is operating properly. The UVLO circuit has a de-glitch feature so that it will typically ignore undershoot transients on the input if they are less than 50 µ s duration.

Minimum Load

The TPS799xx is stable and well-behaved with no output load. To meet the specified accuracy, a minimum load of 500 µ A is required. Below 500 µ A at junction temperatures near +125 ° C, the output can drift up enough to cause the output pull-down to turn on. The output pull-down will limit voltage drift to 5% typically but ground current could increase by approximately 50 µ A. In typical applications, the junction cannot reach high temperatures at light loads since there is no appreciable dissipated power. The specified ground current would then be valid at no load in most applications.

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, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
