7.5A ULTRA LOW DROPOUT POSITIVE
ADJUSTABLE REGULATOR
The US1175 product is a
7.5A regulator with extremely
low dropout voltage using a proprietary Bipolar pro-
cess
that achieves comparable equivalent on re-
sistance to that of discrete MOSFETs
. This product is
specifically designed to provide well regulated supply for
applications requiring 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 associated with switching
regulators
. One such application is the new graphic
chip sets that requires 2.7V supply such as the Intel
I740 chip set.
DESCRIPTION
