TK116xxU

THREE-TERMINAL VOLTAGE REGULATOR

FEATURES

■ Low Dropout Voltage

■ Very Low Standby Current (No Load)

■ Good Load Regulation

■ Internal Thermal Shutdown

■ Short Circuit Protection

■ 3% Output Voltage Accuracy

■ Customized Versions Are Available

DESCRIPTION

The TK116xxU series devices are low dropout, linear 3­terminal regulators.

An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 160 mV at 80 mA load
current).

The regulated output voltages of 3, 3.3, 5 and 9 V are
available. The device has very low (400 µA) quiescent
current with no load and 2 mA with 60 mA load.

APPLICATIONS

■ Battery Powered Systems

■ Portable Consumer Equipment

■ Cordless Telephones

■ Personal Communications Equipment

■ Portable Instrumentation

■ Radio Control Systems

■ Toys

■ Low Voltage Systems

An internal thermal shutdown circuit limits the junction
temperature to below 150 °C. The load current is internally
monitored and the device will shut down in the presence
of a short circuit at the output.

The TK116xxU is available in the SOT-89 surface mount
package.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS

LINE REGULATION (Line Reg)

Line regulation is the ability of the regulator to maintain a
constant output voltage as the input voltage changes. The
line regulation is specified as the input voltage is changed
from VIN = V

OUT(TYP)

+ 1 V to VIN = V

OUT(TYP)

+ 6 V.

LOAD REGULATION (Load Reg)

Load regulation is the ability of the regulator to maintain a
constant output voltage as the load current changes. It is
a pulsed measurement to minimize temperature effects
with the input voltage set to VIN = V

OUT(TYP)

+1 V. The load
regulation is specified under three output current step
conditions of 0 mA to 30 mA, 0 mA to 100 mA and 0 mA to
150 mA.

DROPOUT VOLTAGE (V

DROP

)

This is a measure of how well the regulator performs as the
input voltage decreases. The smaller the number, the
further the input voltage can decrease before regulation
problems occur. Nominal output voltage is first measured
when VIN = V

OUT(TYP)

+ 1 V at a chosen load current. When
the output voltage has dropped 100 mV from the nominal,
VIN - V

is the dropout voltage. This voltage is affected

OUT

by load current and junction temperature.

GROUND CURRENT (I

GND

)

Ground current is the current which flows through the
ground pin(s). It is defined as IIN - I

, excluding control

OUT

current.

PACKAGE POWER DISSIPATION (PD)

This is the power dissipation level at which the thermal
sensor is activated. The IC contains an internal thermal
sensor which monitors the junction temperature. When
the junction temperature exceeds the monitor threshold of
150 °C, the IC is shut down. The junction temperature
rises as the difference between the input power (VIN x IIN)
and the output power (V

OUT

x I

) increases. The rate of

OUT

temperature is greatly affected by the mounting pad
configuration on the PCB, the board material and the
ambient temperature. When the IC mounting has good
thermal conductivity, the junction temperature will be low,
even if the power dissipation is great. When the radiation
of heat is good, the device temperature will be low, even if
the power loss is great. When mounted on the
recommended mounting pad, the power dissipation of the
SOT-89 package is 1000 mW. Derate the power dissipation
at 8 mW/°C for operation above 25 °C. To determine the
power dissipation for shutdown when mounted, attach the
device on the actual PCB and deliberately increase the
output current (or raise the input voltage) until the thermal
protection circuit is activated. Calculate the power
dissipation of the device by subtracting the output power
from the input power. The measurements should allow for
the ambient temperature of the PCB. The value obtained
from PD /(150 °C - TA) is the derating factor. The PCB
mounting pad should provide maximum thermal
conductivity in order to maintain low device temperatures.
As a general rule, the lower the temperature, the better the
reliability of the device. The thermal resistance when
mounted is expressed as follows:

OUTPUT NOISE VOLTAGE

Tj = ΘjA x PD + T

A

This is the effective AC voltage that occurs on the output
voltage under the condition where the input noise is low
and with a given load, filter capacitor, and frequency
range.

For Toko ICs, the internal limit for junction temperature is
150 °C. If the ambient temperature (TA) is 25 °C, then:

THERMAL PROTECTION

150 °C = ΘjA x PD + 25 °C

This is an internal feature which turns the regulator off

ΘjA = 125 °C/P

D

when the junction temperature rises above 150 °C. After
the regulator turns off, the temperature drops and the
regulator output turns back on. Under certain conditions,
the output waveform may appear to be an oscillation as the
output turns off and on and back again in succession.

PD is the value when the thermal sensor is activated. A
simple way to determine PD is to calculate VIN x IIN when
the output side is shorted. Input current gradually falls as
temperature rises. You should use the value when the

APPLICATION INFORMATION

INPUT/OUTPUT DECOUPLING CAPACITOR
CONSIDERATIONS

Voltage regulators require input and output decoupling
capacitors. The required value of these capacitors vary
with application. Capacitors made by different
manufacturers can have different characteristics,
particularly with regard to high frequencies and Equivalent
Series Resistance (ESR) over temperature. The type of
capacitor is also important. For example, a 4.7 µF aluminum
electrolytic may be required for a certain application. If a
tantalum capacitor is used, a lower value of 2.2 µF would
be adequate. It is important to consider the temperature
characteristics of the decoupling capacitors. While Toko
regulators are designed to operate as low as -30 °C, many
capacitors will not operate properly at this temperature.
The capacitance of aluminum electrolytic capacitors may
decrease to 0 at low temperatures. This may cause
oscillation on the output of the regulator since some
capacitance is required to guarantee stability. Thus, it is
important to consider the characteristics of the capacitor
over temperature when selection decoupling capacitors.

The ESR is another important parameter. The ESR will
increase with temperature but low ESR capacitors are
often larger and more costly. In general, tantalum capacitors
offer lower ESR than aluminum electrolytic, but new low
ESR aluminum electrolytic capacitors are now available
from several manufacturers. Usually a bench test is
sufficient to determine the minimum capacitance required
for a particular application. After taking thermal
characteristics and tolerance into account, the minimum
capacitance value should be approximately two times this
value. Please note that linear regulators with a low dropout
voltage have high internal loop gains which require care in
guarding against oscillation caused by insufficient
decoupling capacitance. The use of high quality decoupling
capacitors suited for your application will guarantee proper
operation of the circuit.

BOARD LAYOUT

Copper pattern should be as large as possible. Power
dissipation is 1000 mW for SOT-89. A low ESR capacitor
is recommended. For low temperature operation, select a
capacitor with a low ESR at the lowest operating
temperature to prevent oscillation, degradation of ripple
rejection and increase in noise. The minimum
recommended capacitance is 2.2 µF.

APPLICA TION NOTES

Maximize copper foil area connecting to all IC pins for optimum heat conduction. Place input and output bypass capacitors
close to the GND pin.

For best transient behavior and lowest output impedance, use as large a capacitor value as possible. The temperature
coefficient of the capacitance and Equivalent Series Resistance (ESR) should be taken into account. These parameters
can influence power supply noise and ripple rejection. In extreme cases, oscillation may occur. In order to maintain
stability, the output bypass capacitor value should be minimum 1 µF for tantalum electrolytic or 4.7 µF for aluminum
electrolytic at TA = 25 °C.
