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 requir-

ing 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.
