LD39080 - Ultra low drop BICMOS voltage regulator

Datasheet Summary

Description

The LD39080 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 is available.

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

Features

0.8 A guaranteed output current.
Ultra low-dropout voltage (150 mV typ. @ 0.8 A load, 20 mV typ. @150 mA load).
Very low quiescent current (1 mA typ. @ 0.8 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.
ADJ output voltage: 1.22 V to 5.0 V.
Temperature range: - 40 to 125 °C.
Fast dynamic response to line and load changes.
Stable with ceramic.
