7.5A ULTRA LOW DROPOUT POSITIVE

ADJUSTABLE REGULATOR WITH SHUTDOWN INPUT

PRELIMINARY DATASHEET

DESCRIPTION

FEATURES

The US1176 product is a 7.5A regulator with extremely

Guaranteed <TBDV Dropout at 7.5A

Fast Transient Response

1% Voltage Reference Initial Accuracy

low dropout voltage using a proprietary Bipolar pro-

cess that achieves comparable equivalent on re-

sistance 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 de-

vice 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 ap-

plication 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.

Built-in Thermal Shutdown
