AP1184 is a 4A regulator with extremely low dropout voltage.

This product is specifically designed to provide well regulated

supply for applications requiring 2.8V or lower voltages from 3.3V

ATX power supplies where high efficiency of the switch can be

achieved without the cost and complexity associated with

switching regulator. One such application is the new graphic

chipsets that requires anywhere from 2.4V to 2.7V supply.
