FEATURES
Guaranteed <TBDV Dropout at 7.5A Fast Transient Response 1% Voltage Reference Initial Accuracy Built-in Thermal ShutdownDESCRIPTION
The US1176 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. The US1176 also provides a convenient Shutdown pin that allows the regulator to be shutdown and reduce the input current consumption. Unlike the PNP type regulators this device does not have high quiecent current during the start up mode making it ideal for applications where there is limited current capability such operation from the 5V Standby supply of the computer power supply.One application is the new generation of the RDRAM memory that needs to provide 2.5V from 3.3V input and be able to operate from 5VSB as well.APPLICATIONS
