DESCRIPTION
The IRU1050 is a low dropout three-terminal adjustable
regulator with minimum of 5A 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+ termination
for Pentium Pro™ and Klamath™ processor applications.
The IRU1050 is also well suited for other processors
such as Cyrix™ , AMD and Power PC™ applications.
The IRU1050 is guaranteed to have <1.3V dropout 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.
