„ General Description
APE1185 is a 3A 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.
