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.
