Overview

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.

  • 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-controlled electronic shutdown
  • Compatible with ceramic capacitor COUT = 1 µF
  • Internal current and thermal limit
