LP38842-ADJ - Texas Instruments

LP38842-ADJ 1.5A Ultra Low Dropout Adjustable Linear Regulators

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.
