Product Description

DESCRIPTION
The LK112 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.
■ OUTPUT CURRENT UP TO 150mA
■ LOW DROPOUT VOLTAGE (350mV AT IOUT=150mA)
■ 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 ■ WIDE RANGE OF OUTPUT VOLTGAES
■ INTERNAL CURRENT AND THERMAL LIMIT
