Manufacturer: Texas Instruments

Overview: LP38843 www.ti.com SNVS290C – DECEMBER 2004 – REVISED APRIL 2013 LP38843 3A Ultra Low Dropout Linear Regulators Stable with Ceramic Output Capacitors Check for Samples:.

General Description

The LP38843 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.
