LP3891 Datasheet (National Semiconductor) - 0.8A Fast-Response Ultra Low Dropout Linear

LP3891, 0.8A Fast-Response Ultra Low Dropout Linear

The LP3891 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 i
