Description
General part information
LP38502-ADJ Series
TI’s FlexCap low-dropout (LDO) linear regulators feature unique compensation that allow use of any type of output capacitor with no limits on minimum or maximum equivalent series resistance (ESR). The LP38500 and LP38502 series of LDOs operates from a 2.7-V to 5.5-V input supply. These ultra-low-dropout linear regulators respond very quickly to step changes in load, making them suitable for low-voltage microprocessor applications. Developed on a CMOS process (utilizing a PMOS pass transistor) the LP38500-ADJ and LP38502-ADJ have low quiescent currents that changes little with load current.
