LD39050 - 500mA low quiescent current and low noise voltage regulator

General Description

The LD39050 provides 500 mA maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV.

Stability is given by ceramic capacitors.

Key Features

  • Input voltage from 1.5 to 5.5 V.
  • Ultra low-dropout voltage (200 mV typ. at 500 mA load).
  • Very low quiescent current (20 µA typ. at no load, 100 µA typ. at 500 mA load, 1 µA max. in OFF mode).
  • Very low noise without bypass capacitor.
  • Output voltage tolerance: ± 2.0% @ 25 °C.
  • 500 mA guaranteed output current.
  • Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step and adjustable from 0.8 V.
  • Logic-c.
