DESCRIPTION  
TheTK112xxBisalowdropoutlinearregulatorwithabuilt-  
in electronic switch. The internal switch can be controlled  
byTTLorCMOSlogiclevels. Thedeviceisinthe“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.  
The TK112xxB is available in either a 6-pin SOT-23L or a  
5-pin SOT-89 surface mount package.

An internal PNP pass transistor is used to achieve a low  
dropout voltage of 80 mV (typ.) at 30 mA load current. The  
TK112xxB has a very low quiescent current of 170 µA at  
no load and 1 mA with a 30 mA load. The standby current  
istypically100nA. Theinternalthermalshutdowncircuitry  
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 or overcurrent  
condition at the output.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS  
QUIESCENT CURRENT (IQ)  
OUTPUT VOLTAGE (VOUT  
)
The quiescent current is the current which flows through  
thegroundterminalundernoloadconditions(IOUT =0mA).  
The output voltage is specified with VIN = (VOUT(TYP) + 1 V)  
and IOUT = 30 mA.  
DROPOUT VOLTAGE (VDROP  
)
GROUND CURRENT (IGND  
)
The dropout voltage is the difference between the input  
voltage and the output voltage at which point the regulator  
starts to fall out of regulation. Below this value, the output  
voltage will fall as the input voltage is reduced. It is  
dependent upon the load current and the junction  
temperature.  
Ground current is the current which flows through the  
ground pin(s). It is defined as IIN - IOUT, excluding ICONT  
.
RIPPLE REJECTION RATIO (RR)  
Ripple rejection is the ability of the regulator to attenuate  
the ripple content of the input voltage at the output. It is  
specified with 100 mVrms, 400 Hz superimposed on the  
input voltage, where VIN = VOUT + 1.5 V. The output  
decoupling capacitor is set to 10 µF, the noise bypass  
capacitor is set to 0.1 µF, and the load current is set to 30  
mA. Ripple rejection is the ratio of the ripple content of the  
output vs. the input and is expressed in dB.  
OUTPUT CURRENT (IOUT(MAX)  
)
This is the maximum continuous output current specified  
under the condition where the output voltage drops 0.3 V  
below the value specified with IOUT = 30 mA. The input  
voltage is set to VOUT +1 V, and the current is pulsed to  
minimize temperature effect.  
STANDBY CURRENT (ISTBY  
)
CONTINUOUS OUTPUT CURRENT (IOUT  
)
Standbycurrentisthecurrentwhichflowsintotheregulator  
when the output is turned off by the control function  
(VCONT = 0 V). It is measured with VIN = 8 V (9 V for the 8  
V output device).

PULSE OUTPUT CURRENT (IOUT(PULSE)  
)
SENSOR CIRCUITS  
Overcurrent Sensor  
Maximum pulse width 5 ms at VOUT upper 2.0 V; 7 ms. at  
VOUT under 1.9 V; duty cycle 12.5%: pulse load only.  
LINE REGULATION (Line Reg)  
The overcurrent sensor protects the device in the event  
that the output is shorted to ground.  
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 = VOUT(TYP) + 1 V to VIN = VOUT(TYP) + 6 V.  
Thermal Sensor  
The thermal sensor protects the device in the event that  
the junction temperature exceeds the safe value (TJ = 150  
°C). Thistemperaturerisecanbecausedbyexternalheat,  
excessive power dissipation caused by large input to  
output voltage drops, or excessive output current. The  
regulator will shut off when the temperature exceeds the  
safe value. As the junction temperatures decrease, the  
regulatorwillbegintooperateagain. Undersustainedfault  
conditions, the regulator output will oscillate as the device  
turns off then resets. Damage may occur to the device  
under extreme fault conditions.  
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 = VOUT +1 V. The load  
regulation is specified under two output current step  
conditions of 1 mA to 60 mA and 1 mA to 100 mA.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.)  
Reverse Voltage Protection  
If the control function is not used, connect the control  
terminal to VIN. When the control function is used, the  
control current can be reduced by inserting a series  
resistor (RCONT) between the control terminal and VIN. The  
value of this resistor should be determined from the graph  
below.  
Reverse voltage protection prevents damage due to the  
output voltage being higher than the input voltage. This  
faultconditioncanoccurwhentheoutputcapacitorremains  
charged and the input is reduced to zero, or when an  
external voltage higher than the input voltage is applied to  
the output side.

ON/OFF RESPONSE WITH CONTROL AND LOAD TRANSIENT RESPONSE  
The turn-on time depends upon the value of the output capacitor and the noise bypass capacitor. The turn-on time will  
increase with the value of either capacitor. The graphs below show the relationship between turn-on time and load  
capacitance. If the value of these capacitors is reduced, the load and line regulation will suffer and the noise voltage will  
increase. If the value of these capacitors is increased, the turn-on time will increase.

REDUCTION OF OUTPUT NOISE  
Although the architecture of the Toko regulators is designed to minimize semiconductor noise, further reduction can be  
achieved by the selection of external components. The obvious solution is to increase the size of the output capacitor.  
A more effective solution would be to add a capacitor to the noise bypass terminal. The value of this capacitor should  
be 0.1 µf or higher (higher values provide greater noise reduction). Although stable operation is possible without the noise  
bypass capacitor, this terminal has a high impedance and care should be taken to avoid a large circuit area on the printed  
circuit board when the capacitor is not used. Please note that several parameters are affected by the value of the  
capacitors and bench testing is recommended when deviating from standard values.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.)  
the output side is shorted. Input current gradually falls as  
temperature rises. You should use the value when thermal  
equilibrium is reached.  
PACKAGE POWER DISSIPATION (PD)  
This is the power dissipation level at which the thermal  
sensor is activated. The IC contains an internal thermal  
sensorwhichmonitorsthejunctiontemperature. Whenthe  
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 (VOUT x IOUT) increases. The rate of  
temperature rise 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 mounted on  
the recommended mounting pad, the power dissipation of  
the SOT-23L is increased to 600 mW. For operation at  
ambient temperatures over 25 °C, the power dissipation of  
the SOT-23L device should be derated at 4.8 mW/°C. The  
power dissipation of the SOT-89 package is 900 mW when  
mounted as recommended. Derate the power dissipation  
at 7.2 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. These measurements should allow  
fortheambienttemperatureofthePCB.Thevalueobtained  
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:  
The range of usable currents can also be found from the  
graph below.

Procedure:  
1) Find PD  
2) PD1 is taken to be PD x (~0.8 - 0.9)  
3) Plot PD1 against 25 °C  
4) Connect PD1 to the point corresponding to the 150 °C  
with a straight line.  
5) In design, take a vertical line from the maximum  
operating temperature (e.g., 75 °C) to the derating  
curve.  
6) Read off the value of PD against the point at which the

Tj = 0jA x PD + TA  
IOUT = (DPD / (VIN(MAX) - VOUT  
)
For Toko ICs, the internal limit for junction temperature is  
150 °C. If the ambient temperature (TA) is 25 °C, then:  
150 °C = 0jA x PD + 25 °C  
0jA = 125 °C/ PD  
PD is the value when the thermal sensor is activated. A  
simple way to determine PD is to calculate VIN x IIN when

APPLICATION NOTE  
Copper pattern should be as large as possible. Power dissipation is 600 mW for SOT-23L and 900 mV for SOT-89. A  
low Equivalent Series Resistance (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.

In general, the capacitor should be at least 1 µF (aluminum electrolytic) and be rated for the actual ambient operating  
temperature range. The table below shows typical characteristics for several types and values of capacitance. Please  
note that the ESR varies widely depending upon manufacturer, type, size, and material.
