AP7175
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.
