DESCRIPTION
The TK112xxA is a low dropout linear regulator with a built-
in electronic switch. The internal switch can be controlled
by TTL or CMOS logic levels. The device is in the ON state
when the control pin is pulled to a logic high level. An
external capacitor can be connected to the noise bypass
pin to lower the output noise level to 30 µVrms.

An internal PNP pass transistor is used to achieve a low
dropout voltage of 70 mV (typ.) at 30 mA load current. The
TK112xxA has a very low quiescent current of 180 µA at no
load and 1 mA with a 30 mA load. The standby current is
typically 100 nA. The internal thermal shutdown circuitry
limits the junction temperature to below 150 °C. The load
currentisinternallymonitoredandthedevicewillshutdown
in the presence of a short circuit or overcurrent condition at
the output.

Note 1: Power dissipation is 400 mW when mounted as recommended. Derate at 3.2 mW/°C for TA > 25 °C.
Note 2: Power dissipation is 800 mW when mounted as recommended. Derate at 6.4 mW/°C for TA > 25 °C.
Note 3: This is a pulse measurement where TJ is constant. The output change due to temperature is not included.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS
the SOT-23L is increased to 400 mW. For operation at
ambient temperatures over 25 °C, the power dissipation of
the SOT-23L device should be derated at 3.2 mW/°C. The
power dissipation of the SOT-89-5 package is 800 mW
when mounted as recommended. Derate the power dissi-
pation at 6.4 mW/°C for operation above 25 °C. To
determine the power dissipation for shutdown when
mounted, attach the device on the actual PCB and deliber-
ately 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. These measurements
should allow for the ambient temperature of the PCB. The
LINE REGULATION (LINE REG)
Line regulation is the relationship between change in
output voltage due to a change in input voltage.
LOAD REGULATION (LOAD REG)
Load regulation is the relationship between change in
output voltage due to a change in load current.
DROP OUT 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
value obtained from PD/(150 °C - T ) is the derating factor.
A
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:
when V = V
+ 1 at a chosen load current. When the
IN
OUT
output voltage has dropped 100 mV from the nominal, V
IN
- V
is the dropout voltage. This voltage is affected by
OUT
load current and junction temperature.

OUTPUT NOISE VOLTAGE
For Toko ICs, the internal limit for junction temperature is
150 °C. If the ambient temperature, T is 25 °C, then:
This is the effective AC voltage that occurs on the output

INPUT/OUTPUT DECOUPLING CAPACITOR CONSIDER-
ATIONS
500
Voltage regulators require input and output decoupling
capacitors. The required value of these capacitors vary
withapplication. Capacitorsmadebydifferentmanufactur-
ers can have different characteristics, particularly with
regardtohighfrequenciesandequivalentresistance(ESR)
over temperature. The type of capacitor is also important.
For example, a 4.7 µF aluminum electrolytic may be re-
quired for a certain application. If a tantalum capacitor is
used, a lower value of 2.2 µF would be adequate. It is
importanttoconsiderthetemperaturecharacteristicsofthe
decoupling capacitors. While Toko regulators are de-
signedtooperateaslowas-40°C, manycapacitorswillnot
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 guar-
antee stability. Thus, it is important to consider the charac-
teristics of the capacitor over temperature when selection
decoupling capacitors. The ESR is another important
parameter. TheESRwillincreasewithtemperaturebutlow
ESR capacitors are often larger and more costly. In
general, Tantalum capacitors offer lower ESR than alumi-
num 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. The recommended minimum capaci-
tance for the TK112xxA is 2.2 µF. Please note that linear
regulators with a low dropout voltage have high internal
loop gains which requires care in guarding against oscilla-
tion caused by insufficient decoupling capacitance. The
use of high quality decoupling capacitors suited for your
application will guarantee proper operation of the circuit.
NOISE BYPASS CAPACITOR SECTION
The noise bypass capacitor (C ) should be connected as
P
close as possible to pin 3 and ground. The recommended
value for C is 0.01 µF. The noise bypass terminal has a
P
high impedance and care should be taken if the noise
bypass capacitor is not used. This terminal is susceptible
to external noise and oscillation can occur when C is not
P
used and the solder pad for this pin is made too large.
