LD39150 - Ultra low drop BICMOS voltage regulator

General Description

The LD39150 is a fast ultra low drop linear regulator which operates from 2.5 V to 6 V input supply.

A wide range of output options are available.

The low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage microprocessor and memory applications.

Key Features

  • 1.5 A guaranteed output current.
  • Ultra low dropout voltage (200 mV typ. @ 1.5 A load, 40 mV typ. @ 300 mA load).
  • Very low quiescent current (1 mA typ. @ 1.5 A load, 1 µA max @ 25 °C in off mode).
  • Logic-controlled electronic shutdown.
  • Current and thermal internal limit.
  • 1.5% output voltage tolerance @ 25 °C.
