LDO REGULATOR WITH ON/OFF SWITCH
TK113xxCM
1. DESCRIPTION
4. PIN CONFIGURATION
The TK113xxC series of low dropout (LDO) voltage
regulators are designed for use in battery-powered
equipment, portable communication devices or RF
modules requiring a thermal enhanced SOT23L-6
package. The power dissipation rating is 600mW.
Features include an operating voltage range of +1.8V to
+14V and an output voltage range of 1.5V to 10.0V in
0.1V steps. The maximum continuous current power
rating is 380mA. The load current is internally monitored
and the device will shut down in the attendance of a short
circuit, over-current condition at the output or a junction
temperature exceeds 150ºC.

An internal PNP pass transistor is used to achieve a
typical low dropout voltage of 105mV (typ.) at 100mA
load current and a standby current of typically 0.1µA at
no load.. An external capacitor can be connected to the
noise bypass pin to lower the output noise level to
45µVrms. This device is stable with low ESR ceramic
capacitors.
*2pin,5pin are connected in the IC.

*1: The minimum operating Voltage for Vin can be 1.8 V. Also, the minimum voltage required for Vin is
Vin = Vdrop + Vout . As a result, operating at Vout = 2.0 V at the minimum operating voltage is not preferred.
*2: The maximum output current is limited by power dissipation.
*3: The input current decreases to the pA level by connecting the control terminal to GND (Off state).
General Note : Parameters with only typical values are just reference. (Not guaranteed)
General Note : It is possible to decrease the output noise voltage by connecting a capacitor with the noise bypass pin
(Np). The noise level is dependent on the capacitance and capacitor characteristic.

13. APPLICATIONS INFORMATION
13-1. Stability
The input capacitor is necessary when the battery is
discharged, the power supply impedance increases, or the
line distance to the power supply is long.
This capacitor might be necessary on each individual IC
even if two or more regulator ICs are used. It is not
possible to determine this indiscriminately. Please
confirm the stability while mounted
Linear regulators require input and output capacitors in
order to maintain the regulator's loop stability. If a 0.1mF
capacitor is connected to the output side, the IC provides
stable operation at any voltage in the practical current
region. However, increase the CL capacitance when
using the IC in the low current region and low voltage.
Otherwise, the IC oscillates.
The equivalent series resistance (ESR) of the output
capacitor must be in the stable operation area. However,
it is recommended to use as large a value of capacitance
as is practical. The output noise and the ripple noise
decrease as the capacitance value increases. ESR values
vary widely between ceramic and tantalum capacitors.
However, tantalum capacitors are assumed to provide
more ESR damping resistance, which provides greater
circuit stability. This implies that a higher level of circuit
stability can be obtained by using tantalum capacitors
when compared to ceramic capacitors with similar values.
A recommended value of the application is as follows.
Cin=CL ³ 0.22mF at Iout ³ 0.5mA
Vin
Vout
TK113xxCM
Cin³0.22mF
CL³0.22mF

However, above recommended value does not satisfy
some conditions.
See “Output Voltage, Output Current vs. Stable
Operation Area“ on the next page.
Select the CL capacitance according to the condition of
use.
If the fast load transient response is necessary, increase
the CL capacitance as much as possible.

The above graphs show stable operation with a ceramic
capacitor of 0.1mF (excluding the low current region). If
the capacitance is not increased in the low voltage, low
current area, stable operation may not be achieved. Please
select the best output capacitor according to the voltage
and current used. The stability of the regulator improves if
a big output side capacitor is used (the stable operation
area extends.) Please use as large a capacitance as is
practical. Although operation above 150mA has not been
described, stability is equal to or better than operation at
150mA.

13-2. Definition of term
¨ Over Current Sensor
¨ Output Voltage (Vout)
The over current sensor protects the device when there is
excessive output current. It also protects the device if the
output is accidentally connected to ground. (When
external transistor is used, the protection operates at 10mA
at the base terminal)
The output voltage is specified with Vin=(VoutTYP+1V)
and Iout=5mA.
¨ Maximum Output Current (Iout MAX)
The rated output current is specified under the condition
where the output voltage drops 0.9V times the value
specified with Iout=5mA. The input voltage is set to
VoutTYP+1V and the current is pulsed to minimize
temperature effect.
¨ Thermal Sensor
The thermal sensor protects the device in case 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.
¨ Dropout Voltage (Vdrop)
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.
Please prevent the loss of the regulator when this
protection operates, by reducing the input voltage or
providing better heat efficiency.
¨ Line Regulation (LinReg)
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=VoutTYP+1V to Vin=VoutTYP+6V. It is a pulse
measurement to minimize temperature effect.
* In the case that the power, Vin ´ Ishort(Short Circuit Current),
becomes more than twice of the maximum rating of its power
dissipation in a moment, there is a possibility that the IC is
destroyed before internal thermal protection works.
¨ Load Regulation (LoaReg)
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=VoutTYP+1V. The load
regulation is specified under an output current step
condition of 5mA to 100mA.
¨ 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
¨ Ripple Rejection (R.R)
Ripple rejection is the ability of the regulator to attenuate
the ripple content of the input voltage at the output. It is
specified with 500mVrms, 1kHz super-imposed on the
input voltage, where Vin=Vout+2V. Ripple rejection is the
ratio of the ripple content of the output vs. input and is
expressed in dB.
¨ ESD
MM : 200pF 0W 200V or more
HBM : 100pF 1.5kW 2000V or more
¨Standby Current (Istandby)
Standby current is the current which flows into the
regulator when the output is turned off by the control
function (Vcont=Vin).

How to determine the thermal resistance when
mounted on PCB
13-3. Layout
The thermal resistance when mounted is expressed as
follows:
Vout
Vin
Tj=qja´Pd+Ta
Tj of IC is set around 150°C. Pd is the value when the
thermal sensor is activated.
If the ambient temperature is 25°C, then:
150=qja´Pd+25
qja=125/Pd (°C /mW)
on/off
Pd is easily calculated.
Mount the IC on the print circuit board. Short between the
output pin and ground. after that, raise input voltage from
0V to evaluated voltage (see*1) gradually.
At shorted the output pin, the power dissipation PD can be
expressed as Pd=Vin ´ Iin.
PCB Material : Glass epoxy (t=0.8mm)
Please do derating with 4.8mW/°C at Pd=600mW and
25°C or more. Thermal resistance (qja) is=208°C/W.
The input current decreases gradually as the temperature
of the chip becomes high. After a while, it reaches the
thermal equilibrium. Use this currrent value at the thermal

The package loss is limited at the temperature that the
internal temperature sensor works (about 150°C).
Therefore, the package loss is assumed to be an internal
limitation. There is no heat radiation characteristic of the
package unit assumed because of the small size. Heat is
carried away by the device being mounted on the PCB.
This value changes by the material and the copper pattern
etc. of the PCB. The losses are approximately 600mW.
Enduring these losses becomes possible in a lot of
applications operating at 25°C.

Procedure (When mounted on PCB.)
1. Find Pd (Vin´Iin when the output side is short-circuited).
2. Plot Pd against 25°C.
3. Connect Pd to the point corresponding to the 150°C with a
straight line.
The overheating protection circuit operates when there are
a lot of losses with the regulator (When outside
temperature is high or heat radiation is bad). The output
current cannot be pulled enough and the output voltage
will drop when the protection circuit operates. When the
junction temperature reaches 150°C, the IC is shut down.
However, operation begins at once when the IC stops
operation and the temperature of the chip decreases.
4. In design, take a vertical line from the maximum operating
temperature (e.g., 75°C) to the derating curve.
5. 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.
6. DPd ¸ (Vinmax-Vout)=Iout (at 75°C)
The maximum output current at the highest operating
temperature will be Iout @ DPd ¸ (VinMax-Vout).
Please use the device at low temperature with better
radiation. The lower temperature provides better quality.

It is recommended to turn the regulator Off when the
circuit following the regulator is non-operating. A design
with little electric power loss can be implemented. We
recommend the use of the on/off control of the regulator
without using a high side switch to provide an output from
the regulator. A highly accurate output voltage with low
voltage drop is obtained.

The pull-up resister is not built-in at control terminal. If a

The above figure is multiple regulators being controlled by
a single On/Off control signal. There is fear of overheating,
because the power loss of the low voltage side IC
(TK11320CM) is large. The series resistor (R) is put in the
input line of the low output voltage regulator in order to
prevent over-dissipation. The voltage dropped across the
resistor reduces the large input-to-output voltage across
the regulator, reducing the power dissipation in the device.
When the thermal sensor works, a decrease of the output
If the control function is not used, connect the control
terminal to GND.
It is possible to reduce the control current by inserting a
series resister (Rc). However, be careful the ON/OFF level

13-5. Noise Bypass
The noise and the ripple rejection characteristics depend
on the capacitance on the Np terminal.
The ripple rejection characteristic of the low frequency
region improves by increasing the capacitance of Cnp.
A standard value is Cnp=0.1mF. Increase Cnp in a design
with important output noise and ripple rejection
requirements. The IC will not be damaged if the capacitor
value is increased.
The on/off switching speed changes depending on the Np
terminal capacitance. The switching speed slows when the
capacitance is large.
