FEATURES DESCRIPTION
El Guaranteed < 1.3V Dropout at Full Load Current The IRU1030 is a low dropout three-terminal adjustable
El Fast Transient Response regulator with minimum of 3A output current capability.
Cl 1% Voltage Reference Initial Accuracy This product is specifically designed to provide well regu-
Cl Output Current Limiting Iated supply for low voltage IC applications such as
Cl Built-ln Thermal Shutdown PentiumTM P54CTM, PSSCTM as well as GTL+ termina-
tion for Pentium ProTM and KlamathTM processor appli-
cations. The IRU1030 is also well suited for other pro-
cessors such as CyrixTM, AMD and Power PCTM 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.
