products (Note 1)
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.
