DESCRIPTION

The IRU1150 is a 4A regulator with extremely low drop out voltage using a proprietary bipolar process that achieves comparable equivalent on-resistance to that of discrete MOSFETs. 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 with out the cost and complexity associated with switching regulators. One such application is the new graphic chip sets that require anywhere from 2.4V to 2.7V supply such as the Intel I740 chip set.
