DESCRIPTION
The IRU1030 is a low dropout three-terminal adjustable
regulator with minimum of 3A output current capability.
This product is specifically designed to provide well regu-
lated 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 IRU1030 is also well suited for other pro-
cessors such as Cyrix™ , AMD and Power PC™ appli-
cations. The IRU1030 is guaranteed to have <1.3V drop-
out at full load current making it ideal to provide well
regulated outputs of 2.5V to 3.3V with 4.75V to 7V input
supply.
