General Description

AP1186 is a 1.5A 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 a

switcher can be achieved without the cost and

complexity associated with switching regulator. One

such application is the new graphic chip sets that

require anywhere from 2.4V to 2.7V supply.
