Product details

Description

SOT23-5L The LK112S is a low-dropout linear regulator with shutdown function.The internal switch can be controlled by TTL or CMOS logic levels.The device is ON when the control pin is pulled to a high logic level.An external capacitor can be connected to the noise bypass pin to reduce the output noise level to 30 µVrms.An internal PNP pass transistor is used to achieve a low-dropout voltage.

Features

Output current up to 200 mA.
Low-dropout voltage (500 mV max. at IOUT = 200 mA).
Very low quiescent current: 0.1 µA in OFF mode and max. 250 µA in ON mode at IOUT = 0 mA.
Low output noise: typ. 30 µV at IOUT = 60 mA and 10 Hz < f < 80 kHz The LK112S has a very low quiescent current in ON mode while in OFF mode the Iq is reduced to 100 nA max. The internal thermal shutdown circuitry limits the junction temperature below 150 °C. The load current is inter.
