The LP38852-ADJ is a high current, fast response regulator
which can maintain output voltage regulation with extremely
low 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 architecture consumes extremely low quiescent
current at any output load current. The use of an N-MOS
power transistor results in wide bandwidth, yet minimum external
capacitance is required to maintain loop stability.
