SNVS225H – FEBRUARY 2003 – REVISED JUNE 2015 LP387x 0.8-A Fast Ultra-Low-Dropout Linear Regulators
1 Features 3 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. The devices are
developed on a CMOS process which allows low
quiescent current operation independent of output
load current. This CMOS process also allows the
LP3871 and LP3874 to operate under extremely low
dropout conditions. 1 Input Voltage: 2.5 V to 7 V
Ultra-Low-Dropout Voltage
Low Ground Pin Current
Load Regulation of 0.04%
10-nA Quiescent Current in Shutdown Mode
Specified Output Current of 0.8-A DC …
