1.5A Fast Response Ultra Low Dropout Linear

Regulators

 

 

 

General Description

The LP3852/LP3855 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 LP3852/LP3855

are developed on a CMOS process which allows low quiescent current operation independent of output load current.

This CMOS process also allows the LP3852/LP3855 to operate under extremely low dropout conditions.

Dropout Voltage: Ultra low dropout voltage; typically 24mV

at 150mA load current and 240mV at 1.5A load current.

Ground Pin Current: Typically 4mA at 1.5A load current.

Shutdown Mode: Typically 10nA quiescent current when

the shutdown pin is pulled low.

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).
