LP3871/LP3874

0.8A Fast Ultra Low Dropout Linear Regulators

General Description

Features

n Ultra low dropout voltage

n Low ground pin current

The LP3871/LP3874 series of fast ultra low-dropout linear

regulators operate from a +2.5V to +7.0V input supply. Wide

range of preset output voltage options are available. These

ultra low dropout linear regulators respond very quickly to

step changes in load, which makes them suitable for low

voltage microprocessor applications. The LP3871/LP3874

are developed on a CMOS process which allows low quies-

cent current operation independent of output load current.

This CMOS process also allows the LP3871/LP3874 to op-

erate under extremely low dropout conditions.

n Load regulation of 0.04%

n 10nA quiescent current in shutdown mode

n Guaranteed output current of 0.8A DC

n Available in TO-263, TO-220 and SOT-223 packages

n Output voltage accuracy 1.5%

n Error flag indicates output status

n Sense option improves load regulation

n Minimum output capacitor requirements

n Overtemperature/overcurrent protection

n −40˚C to +125˚C junction temperature range

Dropout Voltage: Ultra low dropout voltage; typically 24mV

at 80mA load current and 240mV at 0.8A load current.

Ground Pin Current: Typically 6mA at 0.8A load current.

Shutdown Mode: Typically 10nA quiescent current when

the shutdown pin is pulled low.

Applications

n Microprocessor power supplies

n GTL, GTL+, BTL, and SSTL bus terminators

n Power supplies for DSPs

n SCSI terminator

Error Flag: Error flag goes low when the output voltage

drops 10% below nominal value.

SENSE: Sense pin improves regulation at remote loads.

Precision Output Voltage: Multiple output voltage options

are available ranging from 1.8V to 5.0V with a guaranteed

accuracy of 1.5% at room temperature, and 3.0% over all

conditions (varying line, load, and temperature).

n Post regulators

n High efficiency linear regulators

n Battery chargers

n Other battery powered applications

Typical Application Circuits

20063101

*SD and ERROR pins must be pulled high through a 10kΩ pull-up resistor. Connect the ERROR pin to ground if this function is not used. See application hints

for more information.
