illustrate

The LP3882 is a high current, fast response regulator that maintains output voltage regulation with minimal input and output voltage drop. Fabricated in a CMOS process, the device is powered from two input voltages: VBIAS provides the voltage to drive the gate of the N-MOS power transistor, and Vin is the input voltage to the load to power. The use of an external biased railway allows partial operation of voltages from ultra-low input voltages. Unlike bipolar regulators, CMOS architectures draw very low quiescent current at any output load current. The result of using an N-MOS power transistor with a wide bandwidth but minimal external capacitance is the need to maintain loop stability.

The fast transient response of these devices makes them suitable for use in DSPs, microcontroller core voltages, and post-regulator power supply in switching power supplies. Sections are available in TO-220, TO-263 and PSOP-8 packages.

Differential pressure: 110Millivolts (typical) @ 1.5A load current.

Ground pin current: 3mA (typical) at full load.

Shutdown current: 60When the S/D pin of NA (typical) is low.

High-precision output voltage: 1.5%of room temperature accuracy.
