DESCRIPTION

TheTK111xxMisalowdropoutlinearregulatorwithabuilt-

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.

TK111xxM

An internal PNP pass transistor is used to achieve a low

dropout voltage of 85 mV (typ.) at 30 mA load current. The

TK111xxM has a very low quiescent current of 140 µA

(typ.) at no load . The standby current is 100 nA maximum.

The internal thermal shutdown circuitry 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.
