FEATURES  
DESCRIPTION  
TI'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 low-dropout 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.
