Special Purpose Regulators Procurement Notes

Verify component status as the manufacturer lists this part as discontinued or obsolete. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing board layouts before procurement, as replacement components may require design adjustments. Check for updated packaging notifications or lifecycle management documents from Renesas Electronics.

Special Purpose Regulators Selection Notes

Select this component when designing FPGA power architectures requiring three distinct regulated outputs from a single IC. It is suitable for applications prioritizing space efficiency due to its QFN package. Verify that the required output voltage range falls between 0.8V and 3.3V and that the input supply remains within 4.2V to 5.5V. Consider thermal performance and load requirements against the integrated regulator capabilities.

Special Purpose Regulators Part Context

This component belongs to the Intersil (now Renesas) PMIC portfolio, specifically designed for complex digital logic power management. It consolidates multiple linear regulators into one package to simplify schematic design and reduce board area. The series targets high-performance computing and communication equipment where power density is critical.

Special Purpose Regulators Replacement Considerations

Check Renesas official documentation for direct pin-compatible replacements or updated series equivalents. Since the part is listed as obsolete, verify if newer generations offer identical electrical characteristics and package dimensions.
