LP38500/2-ADJ, LP38500A/2A-ADJ 1.5A FlexCap Low Dropout Linear Regulator for 2.7V to 5.5V Inputs May 19, 2008 LP38500/2-ADJ, LP38500A/2A-ADJ 1.5A FlexCap Low Dropout Linear Regulator for 2.7V to 5.5V Inputs General Description National's FlexCap LDO's feature unique compensation that allows the use of any type of output capacitor with no limits on minimum or maximum ESR. The LP38500/2 series of lowdropout linear regulators operates from a +2.7V to +5.5V input supply. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. Developed on a CMOS process, (utilizing a PMOS pass transistor), the LP38500/2 has low quiescent current that changes little with load current.
