Features & Applications

The LK112SM18TR is a 1.8 V output voltage, 200 mA output current, low noise and low drop voltage regulator with shutdown function, available in surface mount SOT-23-5L package.

This device is a low dropout linear regulator with a built in electronic switch.It has a very low quiescent current in ON MODE while in OFF MODE the Iq is reduced down to 100nA max

Features:

  • Output current up to 200 mA
  • Low dropout voltage
  • 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
  • ide range of output voltages
  • nternal current and thermal limit
  • OUT tolerance ± 2% (at 25 °C)
  • Operative input voltage from: VOUT +0.5 to 14 V (for VOUT > 2 V) or from 2.5 V to 14 V (for VOUT < 2 V)
