IRU1075
7.5A LOW DROPOUT POSITIVE
ADJUSTABLE REGULATOR
DESCRIPTION
The IRU1075 is a low dropout three-terminal adjustable
regulator with minimum of 7.5A output current capabil-
ity. This product is specifically designed to provide well
regulated supply for low voltage IC applications such as
Pentium P54C, P55C as well as GTL+ termina-
tion for Pentium Pro and Klamath processor appli-
cations. The IRU1075 is also well suited for other pro-
cessors such as Cyrix, AMD and Power PC appli-
cations. The IRU1075 is guaranteed to have <1.2V drop-
out at full load current making it ideal to provide well
regulated outputs such as 3.3V with input supply volt-
age as low as 4.5V minimum.
