General Description

The S5U1284 is 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 compliexity associated with switching regulator.

One such application is the new graphic chipsets that requires anywhere from 2.4V to 2.7V supply.
