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 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.
