Description

General part information

TPS74401 Series

The TPS74401 low-dropout (LDO) linear regulators provide an easy-to-use robust power-management option for a wide variety of applications. The 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 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.
