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
