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.
