VOLTAGE REGULATOR WITH ON/OFF SWITCH
FEATURES
■ High Voltage Precision at ± 2.0%
■ Active Low On/Off Control
■ Very Low Dropout Voltage 80 mV at 30 mA
■ Very Low Noise
■ Very Small SOT-23L or SOT-89-5 Surface Mount

DESCRIPTION
The TK113xxB is a low dropout linear regulator with a builtin electronic switch. The device is in the ON state when the
control pin is pulled to a low 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 80 mV (typ.) at 30 mA load current. The
TK113xxB has a very low quiescent current of 170 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
current is internally monitored and the device will shutdown
in the presence of a short circuit or overcurrent condition at
the output.

DEFINITION AND EXPLANATION OF TECHNICAL TERMS
OUTPUT VOLTAGE (VO)
The output voltage is specified with VIN = (V
and IO = 30 mA.
DROPOUT VOLTAGE (V
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.
OUTPUT CURRENT (IO MAX)
The rated output current is specified under the condition
where the output voltage drops 0.3 V below the value
specified with IO = 30 mA. The input voltage is set to VO +1
V, and the current is pulsed to minimize temperature effect.
CONTINUOUS OUTPUT CURRENT (IO)
Normal operated output current. This is limited by package
power dissipation.
PULSE OUTPUT CURRENT (I
Max pulsewidth 5ms, Duty cycle 12.5%: pulse load only
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 = VO + 1V to VIN = VO + 6V.
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 = VO +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.
QUIESCENT CURRENT (IQ)
The quiescent current is the current which flows through
the ground terminal under no load conditions (IO = 0 mA)

)
O (PULSE)
)
O(TYP)
+ 1 V)
.
RIPPLE REJECTION RATIO
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 = VO+ 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.
STANDBY CURRENT
Standby current is the current which flows into the regulator
when the output is turned off by the control function (V
= VIN.) It is measured with VIN = 8 V (9 V for the 8 V output
device.)
SENSOR CIRCUIT
Over current sensor
The overcurrent sensor protects the device in the event
that the output is shorted to ground.
Thermal sensor
The thermal sensor protects the device in the event
that the junction temperature exceeds the safe value
(TJ = 150 °C). This temperature rise can be caused by
external heat, 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 regulator will begin to operate
again. Under sustained fault conditions, the regulator
output will oscillate as the device turns off then resets.
Damage may occur to the device under extreme fault
conditions.
Reverse Voltage Protection
Reverse voltage protection prevents damage due to
the output voltage being higher than the input voltage.
This fault condition can occur when the output capacitor remains 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 graph below shows 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.

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 shutdown. The junction temperature rises as the difference between the input power (VIN X IIN) and the output power
(V
X I
OUT
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-89-5 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 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:
) increases. The rate of temperature rise is greatly affected by the mounting pad configuration on the PCB,

TJ = 0JA X PD + T
A
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 X PD = 125 °C
0JA = 125 °C/ P
D
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 thermal equilibrium is
reached.
The range of currents usable can also be found from the graph below.

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 vertical line intersects the derating curve. This is taken as the
maximum power dissipation, DPD.

APPLICATION HINTS
Copper pattern should be as large as possible. Power dissipation is 600 mW for SOT-23L and 900 mV for SOT-89-5. 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.
