DESCRIPTION

The TK111xxS is a low dropout linear regulator with a built-

in electronic switch. The internal switch can be controlled

by TTL or CMOS logic levels. The device is in the “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.

An internal PNP pass transistor is used to achieve a low

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

TK111xxS has a very low quiescent current of 140

µA

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

The internal thermal shut down 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.

The TK111xxS is available in a miniature SOT-23-5 surface

mount package.
