LP38852-ADJ - Texas Instruments

LP38852-ADJ 1.5-A Fast-Response High-Accuracy Adjustable LDO Linear Regulator

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 l.
