LDO REGULATOR WITH ON/OFF SWITCH
TK113xxCM
1. DESCRIPTION
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.

The maximum ratings are the absolute limitation values with the possibility of the IC breakage.
When the operation exceeds this standard, quality can not be guaranteed.

*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.
