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.
