LP38503-ADJ Datasheet | National Semiconductor

Description National's Flex Cap LDO's feature unique pensation that allows the use of any type of output capacitor with no limits on minimum or maximum ESR. The LP38501/3 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 LP38501/3 has low quiescent current that changes little with load current. Ground Pin Current: Typically 2 m A at 3A load current. Disable Mode: Typically 25 n A quiescent current when the Enable pin is pulled low. Simplified pensation: Stable with any type of output capacitor, regardless of ESR. Precision Output: "A" grade versions available with 1.5% VADJ tolerance (25°C) and 3% over line, load and temperature.
