DESCRIPTION
The US1175 product is a 7.5A regulator with extremely low dropout 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 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.

FEATURES
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.
