LP3893 Datasheet (National Semiconductor) - 3A Fast-Response Ultra Low Dropout Linear Regulators

LP3893, 3A Fast-Response Ultra Low Dropout Linear Regulators

The LP3893 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
