Features

General Description

The AP7173 is a 1.5A low-dropout (LDO) linear regulator that

features a user-programmable soft-start, an enable input and a

power-good output.

•

•

•

The soft-start reduces inrush current of the load capacitors and

minimizes stress on the input power source during start-up. The

enable input and power-good output allow users to configure

power management solutions that can meet the sequencing

requirements of FPGAs, DSPs, and other applications with

different start-up and power-down requirements.

•

•

2% accuracy over line, load and temperature range

•

Power-Good (PG) output for supply monitoring and for

sequencing of other supplies

•

Programmable soft-start provides linear voltage startup

•

transient response

The AP7173 is stable with any type of output capacitor of 2.2µF or

more. A precision reference and feedback control deliver 2%

accuracy over load, line, and operating temperature ranges. The

AP7173 is available in both DFN3030-10 and SOP-8L-EP

packages.
