3A ULTRA LOW DROPOUT LINEAR REGULATOR WITH ENABLE

Description

The AP7175 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 AP7175 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 AP7175 is available in SO-8EP and MSOP-8EP package with an

exposed PAD to reduce the junction to case resistance and extend

the temperature range it can be used in.
