General Description
The LP38842 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.
The use of an external bias rail allows the part to operate from ultra low Vin
voltages.
Unlike bipolar regulators, the
CMOS architectu...
