LD39050xx - 500 mA low quiescent current low noise voltage regulator

General Description

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

Stability is provided using 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 ADJ from 0.8 V Logic-controlled electronic shutdown Compatible with ceramic capacitor COUT.
