Special Purpose Regulators Procurement Notes

This component has been officially discontinued by the manufacturer as indicated by Product Change Notification records dated November 2025. Verification of obsolescence status is critical before integration into new designs. Existing inventory may be available through authorized distributors but supply continuity cannot be guaranteed. Designers should confirm end-of-life documentation directly with Renesas Electronics Corporation prior to procurement planning.

Special Purpose Regulators Selection Notes

Engineers selecting this part must account for its discontinued status when designing long-term production systems. The device provides specific compatibility with Intel IMVP-7 and VR12 protocols, making it suitable for legacy or maintenance upgrades rather than new greenfield projects. Alternative solutions within the R3 series should be evaluated for modern requirements, considering the limited future availability of this specific package and configuration.

Special Purpose Regulators Part Context

The ISL95836HRTZ-T belongs to the ISL95836 family of specialized power management ICs manufactured by Renesas Electronics. This series utilizes the Robust Ripple Regulator architecture to address the dynamic load demands of high-speed processors. The HRTZ suffix denotes the tape and reel packaging variant intended for automated surface-mount assembly processes in consumer electronics manufacturing.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available due to the product's discontinuation status. Designers should consult Renesas for recommended cross-reference components or updated series replacements that maintain IMVP-7/VR12 compatibility and similar thermal performance characteristics.
