LP38841 - National Semiconductor

LP38841 0.8A Ultra Low Dropout Linear Regulators Stable

The LP38841 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.
