1.5-A 0.8-V adjustable low-dropout (LDO) voltage regulator with power good and enable

The TPS748A

low-dropout (LDO) linear regulator provides an easy-to-use robust power management

design 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 design to be configured that meets the sequencing requirements

of many applications. Field-programmable gate arrays (FPGAs), digital signal

processors (DSPs), and other applications with special start-up requirements are

some examples that benefit from this complete flexibility.

A precision reference and error amplifier deliver

0.85% accuracy over load, line, temperature, and process. The device is stable with

any type of capacitor greater than or equal to 10µF, and is fully specified for

TJ = –40°C to +125°C. The TPS748A is

offered in a small, 3mm × 3mm, VSON-10 package, yielding a highly compact, total

solution size.
