IRU1176

7.5A ULTRA LOW DROPOUT POSITIVE

ADJUSTABLE REGULATOR WITH SHUTDOWN INPUT

DESCRIPTION

FEATURES

Guaranteed <0.65V Dropout at 7.5A

Fast Transient Response

The IRU1176 is a 7.5A regulator with extremely low drop-

out voltage using a proprietary Bipolar process that

achieves comparable equivalent on resistance to that of

discrete MOSFETs. The IRU1176 also provides a conve-

nient shutdown pin that allows the regulator to be shut-

down and reduce the input current consumption. Unlike

the PNP type regulators this device does not have high

quiescent current during the start up mode making it

ideal for applications where there is limited current ca-

pability such operation from the 5V standby supply of

the computer power supply. One application is the new

generation of RDRAM memory that needs to provide 2.5V

from 3.3V input and be able to operate from 5VSB as

well.
