LP38841-ADJ - National Semiconductor

LP38841-ADJ Ultra Low Dropout Adjustable Linear Regulators Stable

The LP38841-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.
