Special Purpose Regulators Procurement Notes

Verify the specific manufacturer marking and date code against official Infineon documentation to confirm authenticity. Ensure the TO-263 package matches the required footprint. Confirm that the application environment supports the component's operational specifications. Check for any RoHS compliance status variations depending on the production batch. Validate supplier authorization to prevent counterfeit components.

Special Purpose Regulators Selection Notes

Select this component only when designing for or repairing systems utilizing Intel Pentium or P55C processors. Verify that the input voltage range of 2.55V to 7V aligns with the system power rail. Confirm that the TO-263 package size fits the PCB layout constraints. Ensure the thermal requirements of the application are met by the package's dissipation capabilities. Consider the obsolete lifecycle status for long-term availability planning.

Special Purpose Regulators Part Context

The IRU1075CM belongs to the category of special purpose regulators manufactured by Infineon Technologies. It was developed to address the specific power delivery needs of early high-performance microprocessors. As a dedicated IC, it integrates control logic and power stages into one unit. This specialization distinguishes it from general-purpose switching regulators, offering tailored performance for its target processor family.

Special Purpose Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specialized nature of this regulator for specific Intel processors, direct pin-to-pin replacements may not exist. Designers should consult official Infineon archives or authorized distributors for potential obsolescence management strategies.
