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.
