Features & Applications

The LK112SM50TR is a 5 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.The internal switch can be controlled by TTL or CMOS logic levels.

This device is has a very low quiescent current in ON MODE while in OFF MODE the Iq is reduced down to 100nA max. The internal thermal shutdown circuitry limits the junction temperature to below 150 °C.

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
  • Wide range of output voltages
  • Internal current and thermal limit
  • VOUT 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)
