IRU1050

Data Sheet No. PD94126 IRU1050 5A LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR 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 regulated 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. FEATURES Guaranteed < 1.3V Dropout at Full Load Current Fast Transient Response 1% Voltage Reference Initial Accuracy Output Current Limiting Built-In Thermal Shutdown APPLICATIONS Low Voltage Processor Applications such as: P54C™ , P55C™ , Cyrix M2™ , POWER PC™ , AMD GTL+ Termination PENTIUM PRO™ , KLAMATH ™ Low Voltage Memory Termination Applications Standard 3.3V Chip Set and Logic Applications TYPICAL APPLICATION 5V C1 1500uF VIN 3 IRU1050 VOUT 2 R1 121 R2 205 3.38V / 5A C2 2x 1500uF Adj 1 Figure 1 - Typical Application of IRU1050 in a 5V to 3.38V regulator designed to meet the Intel P54C ™ processors.
