DESCRIPTION
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
