The LP38856 is a high-current, fast-response regulator which
can maintain output voltage regulation with an extremely low
input to output voltage drop. Fabricated on a CMOS process,
the device operates from two input voltages: VBIAS provides
power for the internal bias and control circuits, as well as drive
for the gate of the N-MOS power transistor, while VIN 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 architecture consumes extremely low quiescent
current at any output load current. The use of an NMOS
power transistor results in wide bandwidth, yet minimum
external capacitance is required to maintain loop stability.
