DESCRIPTION

The LP3892 is a high current, fast response regulator

which can maintain output voltage regulation with

minimum input to output voltage drop. Fabricated on

a CMOS process, the device operates from two input

voltages: Vbias provides voltage to drive the gate of

the N-MOS power transistor, while Vin is the input

voltage which supplies power to the load. The use of

an external bias rail allows the part to operate from

ultra low Vin voltages. Unlike bipolar regulators, the

CMOS architecture consumes extremely low

quiescent current at any output load current. The use

of an N-MOS power transistor results in wide

bandwidth, yet minimum external capacitance is

required to maintain loop stability.

The fast transient response of these devices makes

them suitable for use in powering DSP,

Microcontroller Core voltages and Switch Mode

Power Supply post regulators. The parts are available

in TO-220, DDPAK/TO-263 and SO PowerPAD-8

packages.

Dropout Voltage:140mV (typ) at 1.5A load current.

Ground Pin Current: 3 mA (typ) at full load.

Shutdown Current: 60 nA (typ) when S/D pin is low.

Precision Output Voltage: 1.5% room temperature

accuracy.
