3 Description

The TPS74401 low-dropout (LDO) linear regulators

provide an easy-to-use robust power-management

option for a wide variety of applications. The userprogrammable

soft-start minimizes stress on the input

power source by reducing capacitive inrush current

on start-up. The soft-start is monotonic and designed

for powering many different types of processors

and application-specific integrated circuits (ASICs).

The enable input and power-good output allow

easy sequencing with external regulators. Complete

flexibility lets the user configure a plan that meets the

sequencing requirements of field-programmable gate

arrays (FPGAs), digital signal processors (DSPs), and

other applications with specific start-up requirements.

A precision reference and error amplifier deliver 1%

accuracy over load, line, temperature, and process.

The device is stable without an output capacitor

(legacy chip) or with any type of capacitor ≥ 2.2μF

(new chip). The device is fully specified from TJ = –

40°C to 125°C.
