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 quiescent
current operation independent of output load current.
This CMOS process also allows the LP3871/LP3874 to operate
under extremely low dropout conditions.
