LK112 - Low noise and low drop voltage regulator

General Description

SOT23-5L

Key Features

  • Output current up to 150 mA.
  • Low-dropout voltage (350 mV at IOUT = 150 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 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 log.
