DESCRIPTION
The TPS74801 low-dropout (LDO) linear regulator
provides an easy-to-use robust power management
solution
for
a
wide
User-programmable soft-start minimizes stress on
the input power source by reducing capacitive inrush
current on start-up. The soft-start is monotonic and
well-suited for powering many different types of
processors
and
ASICs.
power-good output allow easy sequencing with
external regulators. This complete flexibility permits
the user to configure a solution that meets the
sequencing requirements of FPGAs, DSPs, and
other applications with special start-up requirements.
