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 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.  
the output noise level to 30µV . An internal PNP  
rms  
pass transistor is used to achieve a low dropout  
voltage.
