AP7173

1.5A LOW DROPOUT LINEAR REGULATOR WITH

PROGRAMMABLE SOFT-START

General Description

Features

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.

•

Low V_INand wide V_INrange: 1.0V to 5.5V

Bias voltage (V_VCC) range: 2.7V to 5.5V

Low V_OUTrange: 0.8V to 3.3V

Low dropout: 165mV typical at 1.5A, V_VCC= 5V

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

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

Bias supply permits low V_INoperation with good

transient response

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.

•

Stable with any output capacitor ≥ 2.2µF

DFN3030-10 and SOP-8L-EP: available in “Green”

molding compound (No Br, Sb)

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.

•

Lead-free finish/ RoHS Compliant (Note 1)
