 DESCRIPTION
The TPS728xx series of low-dropout linear regulators
(LDOs), with a selectable dual-voltage level output, is
designed specially for applications that require two
levels of output voltage regulation. Programming
fuses and memory cards, reducing leakage effects,
and conserving power in nanometric processes are
some application examples.
The VSET pin is used to select one of two output
voltage levels preset through innovative factory
EEPROM programming. A precision bandgap and
error amplifier provides an overall 3% accuracy over
load, line, and temperature extremes.
Ultra-small wafer chip scale (WCSP) and 2mm x
2mm SON packages make the TPS728xx series ideal
for handheld applications.
This family of devices is fully specified over a
temperature range of T J = – 40 ° C to +125 ° C.
