AP7176B

3A ULTRA LOW DROPOUT LINEAR REGULATOR WITH ENABLE

Description

The AP7176B is a 3.0A ultra low-dropout (LDO) linear regulator that

features an enable input and a power-good output.

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.

The AP7176B features two supply inputs, for power conversion

supply and control. With the separation of the control and the power

input very low dropout voltages can be reached and power dissipation

is reduced.

A precision reference and feedback control deliver 1.5% accuracy

over load, line, and operating temperature ranges.

The AP7176B is available in SO-8EP, MSOP-8EP and U-DFN3030-

10 package with an exposed PAD to reduce the junction to case

resistance and extend the temperature range it can be used in.
