PACKAGE ORDER INFORMATION
TYPICAL APPLICATION
DESCRIPTION
The IRU1261, using a proprietary process, combines a
dual low dropout regulator with fixed outputs of 1.5V and
2.5V in a single package with the 1.5V output having a
minimum of 6A and the 2.5V having a 1A output current
capability. This product is specifically designed to pro-
vide well regulated supplies from 3.3V to generate 1.5V
for GTL+ termination resistor supply and 2.5V clock
supply for the new generation of the Pentium
II
TM
pro-
cessor applications.
