LK112
LK112 is Low noise and low drop voltage regulator manufactured by STMicroelectronics.
Description
SOT23-5L
Features
- Output current up to 150 m A
- Low-dropout voltage (350 m V at IOUT = 150 m A)
- Very low quiescent current:
- 0.1 µA in OFF mode and max. 250 µA in ON mode at IOUT = 0 m A
- Low output noise:
- typ. 30 µV at IOUT = 60 m A and 10 Hz < f < 80 k Hz
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 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. The LK112 has a very low quiescent current in...
