The LP38859 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.
