LP38853 - National Semiconductor

LP38853 Fast-Response High-Accuracy Adjustable LDO Linear Regulator

The LP38853-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 l.
