3 Description
The LP38853 is a high-current, fast-response regulator that 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 NMOS power transistor; VIN is the input...
