LP38513 3A Fast Response Ultra Low Dropout Linear Regulator July 2007 LP38513 3A Fast Response Ultra Low Dropout Linear Regulator General Description The LP38513 fast response ultra low dropout linear regulator operates from a +2.25V to +5.50V input supply. This ultra low dropout linear regulator responds very quickly to step changes in line or load conditions, which makes it suitable for low voltage microprocessor applications. Developed on a CMOS process, with a PMOS pass transistor, the LP38513 has low quiescent current operation that is independent of the output load current. Ground Pin Current: Typically 12 mA at 3A load current. Disable Mode: Typically 60 µA quiescent current when the Enable pin is pulled low.
