LDK220 - 200mA low quiescent current and low noise LDO

Description

The LDK220 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 13.2 V, with a typical dropout voltage of 100 mV.

A ceramic capacitor stabilizes it on the output.

Features

  • Input voltage from 2.5 to 13.2 V.
  • Very low-dropout voltage (100 mV typ. @ 100 mA load).
  • Low quiescent current (typ. 55 µA, 1 µA in off mode).
  • Low noise.
  • Output voltage tolerance: ± 2.0% @ 25 °C.
  • 200 mA guaranteed output current.
  • Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable.
  • Logic-controlled electronic shutdown.
  • Output discharge function.
  • Compa.
