3 Description

The TPS74901 low-dropout (LDO) linear regulator

provides an easy-to-use, robust power management

solution for a wide variety of applications. Userprogrammable

soft-start minimizes stress on the input

power source by reducing capacitive inrush current

during start-up. The soft-start is monotonic and wellsuited

for powering many different types of

processors and ASICs. The enable input and powergood

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.
