DESCRIPTION

The TK113xxB is a low dropout linear regulator with a built-

in electronic switch. The device is in the “on” state when

the control pin is pulled to a low 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 80 mV (typ.) at 30 mA load current. The

TK113xxB has a very low quiescent current of 170

µA

at no

load and 1 mA with a 30 mA load. The standby current is

typically 100 nA. 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.
