Description

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.

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.

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).
