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.
