FEATURES  
DESCRIPTION  
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.
