DESCRIPTION

The LK112S 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 ON state when the control pin is pulled to

a logic high level. An external capacitor can be

used connected to the noise bypass pin to lower

the output noise level to 30

µV

rms. An internal PNP

pass transistor is used to achieve a low dropout

voltage.

The LK112S has a very low quiescent current in

ON MODE while in OFF MODE the Iq is reduced

down to 100nA max. The internal thermal

shutdown circuitry limits the juntion temperature to

below 150°C. The load current is internally

monitored and the device will shutdown in the

presence of a short circuit or overcurrent condition

at the output.
