Description

General part information

TPS748A-Q1 Series

The TPS748A-Q1 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 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 enables 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 greater than or equal to 2.2 µF, and is fully specified for T J = –40°C to +150°C. The TPS748A-Q1 is offered in a small, 3-mm × 3-mm, VSON-10 package, yielding a highly compact, total solution size.
