IRU1175

7.5A ULTRA LOW DROPOUT POSITIVE

ADJUSTABLE REGULATOR

DESCRIPTION

FEATURES

0.5V Dropout at 7.5A (Equivalent of 67mΩ)

Fast Transient Response

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 chip sets that require 2.7V supply such

as the Intel I740 chip set.
