DESCRIPTION

The IRU1175 is a 7.5A regulator with extremely low dropout 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 very low dropout such as 2.8V from 3.3V ATX power supplies where the same efficiency as the switcher can be achieved without the cost and complexity associated with switching regulators. One such application is the new graphic chipsets that requires 2.7V supply such as the Intel I740 chipset.
