7.5A ULTRA LOW DROPOUT POSITIVE
ADJUSTABLE REGULATOR
The IRU1175 is a 7.5A 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 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 associ-
ated with switching regulators. One such application is
the new graphic chipsets that requires 2.7V supply such
as the Intel I740 chipset.
