LP38842-ADJ Datasheet 1.5a Ultra Low Dropout Adjustable Linear Regulators

Manufacturer: Texas Instruments

Overview: LP38842-ADJ www.ti.com SNVS304A – FEBRUARY 2005 – REVISED APRIL 2013 LP38842-ADJ 1.

General Description

The LP38842-ADJ 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.
