7.5A ULTRA LOW DROPOUT POSITIVE

ADJUSTABLE REGULATOR

PRELIMINARY DATASHEET

DESCRIPTION

FEATURES

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.

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

Fast Transient Response

1% Voltage Reference Initial Accuracy

Built-in Thermal Shutdown

APPLICATIONS

3.3V to 2.7V Intel I740 chip set.
