LP396x 800-mA Fast Ultra-Low-Dropout Linear Regulators

1 Features

3 Description

The LP396x series of fast ultra-low-dropout linear

•

Input Supply Voltage: 2.5 V to 7 V

Ultra-Low Dropout Voltage

regulators operate from a 2.5-V to 7-V input supply. A

wide range of preset output voltage options are

available. These ultra-low dropout linear regulators

respond very fast to step changes in load which

makes them suitable for low-voltage microprocessor

applications. The LP3961 and LP3964 are developed

on a CMOS process which allows low quiescent

current operation independent of output load current,

as well as operation under extremely low dropout

conditions.

Low Ground Pin Current

Load Regulation of 0.02%

15-µA Quiescent Current in Shutdown Mode

Specified Output Current of 0.8-A DC

Output Voltage Accuracy ±1.5%

ERROR Flag Indicates Output Status (LP3961)

Sense Option Improves Better Load Regulation

(LP3964)

Dropout Voltage: Ultra-low dropout voltage; typically

24 mV at 80-mA load current and 240 mV at 800-mA

load current.

•

Extremely Low Output Capacitor Requirements

Overtemperature and Overcurrent Protection

−40°C to 125°C Junction Temperature Range

Ground Pin Current: Typically 4 mA at 800-mA load

current.

ERROR Flag: ERROR flag goes low when the output

voltage drops 10% below nominal value (for LP3961).

2 Applications

•

Microprocessor Power Supplies

GTL, GTL+, BTL, and SSTL Bus Terminators

Power Supplies for DSPs

SCSI Terminator

SENSE: SENSE pin improves regulation at remote

loads (for LP3964).

Precision Output Voltage: Multiple output voltage

options are available ranging from 1.2 V to 5 V and

adjustable (LP3964), with a specified accuracy of

±1.5% at room temperature, and ±3% over all

conditions (varying line, load, and temperature).
