LK112S LOW NOISE LOW DROP VOLTAGE REGULATOR WITH SHUTDOWN FUNCTION

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 30µVrms. 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.

■ OUTPUT CURRENT UP TO 200mA
■ LOW DROPOUT VOLTAGE (500mV MAX AT IOUT=200mA)
■ VERY LOW QUIESCENT CURRENT: 0.1µA IN OFF MODE AND MAX 250µA IN ON MODE AT IOUT=0mA
■ LOW OUTPUT NOISE: TYP 30µV AT IOUT=60mA AND 10Hz<f<80KHz
■ WIDE RANGE OF OUTPUT VOLTAGES
■ INTERNAL CURRENT AND THERMAL LIMIT
■ VOUT TOLERANCE ± 2% (AT 25°C)
