General Description

The LP3871 and LP3874 series of fast ultra-lowdropout linear regulators operate from a 2.5-V to 7-V 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.
