Description

General part information

TPS7A74 Series

The TPS7A74 low-dropout (LDO) linear regulator provides an easy-to-use robust power management solution for a wide variety of applications. 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 application-specific integrated circuits (ASICs). The enable input allows for easy sequencing with external regulators. This complete flexibility allows a solution to be configured that meets the sequencing requirements of field-programmable gate arrays (FPGAs), digital signal processors (DSPs), and other applications with special start-up requirements.

A precision reference and error amplifier deliver 1.5% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor greater than or equal to 10 µF, and is fully specified for TJ= –40°C to +125°C. The TPS7A74 is offered in a small, 3-mm × 3-mm, WSON-8 package, yielding a highly compact, total solution size.
