The LP3855-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V
input supply. These ultra low dropout linear regulators respond very quickly to step changes in
load, which makes them suitable for low voltage microprocessor applications. The LP3855-ADJ is
developed on a CMOS process which allows low quiescent current operation independent of output load
current. This CMOS process also allows the LP3855-ADJ to operate under extremely low dropout
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
Shutdown Mode: Typically 10nA quiescent current when the
shutdown pin is pulled low.
Adjustable Output Voltage: The output voltage may be
programmed via two external resistors.
