Description

General part information

TPS74901 Series

The TPS74901 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 during 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. 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 2% accuracy over load, line, temperature, and process. The device is stable with any type of capacitor ≥ 2.2µF, and the device is fully specified from –40°C to +125°C. The TPS74901 is offered in a small (3mm × 3mm) VSON package and a small (5mm × 5mm) VQFN package, yielding a highly compact total solution size. The device is also available in a DDPAK-7 package.
