3 Description

The TPS748A-Q1 low-dropout (LDO) linear regulator

provides an easy-to-use robust power management

solution for a wide variety of applications. 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.

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 TJ

= –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.
