Features
Description
The AP7173 is a 1.5A low-dropout (LDO) linear regulator that
features a user-programmable soft-start, an enable input and
a power-good output.
The soft-start reduces inrush current of the load capacitors
and minimizes stress on the input power source during start-
up. 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
requirements.
The AP7173 is stable with any type of output capacitor of
2.2µF or more. A precision reference and feedback control
deliver
temperature ranges.

... Therefore, the thermal protection circuit may cycle on and off at a rate dependent on the power dissipation, thermal resistance, and ambient temperature. POWER DISSIPATION Thermal shutdown is intented to protect the AP7173 against abnormal overheating.
