General Description

The LP3883isa high-current, fast-response regulator which
can maintain output voltage regulation with minimum inputto
output voltage drop. Fabricatedona CMOS process, the
device operates from two input voltages: Vbias provides
voltageto drive the gateof the N-MOS power transistor,
while Vinis the input voltage which supplies powerto the
load. The useofan external bias rail allows the partto
operate from ultra low Vin voltages. Unlike bipolar regula-
tors,the CMOS architecture consumes extremely low quies-
cent currentat any output load current. The useof an
N-MOS power transistor resultsin wide bandwidth,yet mini-
mum external capacitanceis requiredto maintain loop sta-
bility.
The fast transient responseof these devices makes them
suitablefor usein powering DSP, Microcontroller Core volt-
ages and Switch Mode Power Supply post regulators. The
partsare availablein TO-220 and TO-263 packages.
Dropout Voltage:
210 mV (typ)@3A load current.
Ground Pin Current:
