LP396x 800-mA Fast Ultra-Low-Dropout Linear Regulators Features 3 Description

The LP396x series of fast ultra-low-dropout linear Input Supply Voltage: 2.5Vto7V regulators operate froma 2.5-Vto 7-V input supply.A• Ultra-Low Dropout Voltage wide range of preset output voltage options are• Low Ground Pin Current available. These ultra-low dropout linear regulators
respond very fast to step changesin load which• Load Regulationof 0.02% makes them suitable for low-voltage microprocessor• 15-µA Quiescent Currentin Shutdown Mode applications. The LP3961 and LP3964 are developed• Specified Output Currentof 0.8-A DC ona CMOS process which allows low quiescent
current operation independentof output load current,• Output Voltage Accuracy ±1.5% well as operation under extremely low dropout• ERROR Flag Indicates Output Status (LP3961) conditions.• Sense Option Improves Better Load Regulation
Dropout Voltage:
Ultra-low dropout voltage; typically(LP3964) 24 mVat 80-mA load current and 240 mVat 800-mA• Extremely Low Output Capacitor Requirements load current.• Overtemperature and Overcurrent Protection Ground Pin Current: Typically4 mAat 800-mA load• −40°Cto 125°C Junction Temperature Range current.
ERROR Flag:
ERROR flag goes low when the output2 Applications
voltage drops 10% below nominal value (for LP3961).• Microprocessor Power Supplies
