Special Purpose Regulators Procurement Notes

Verify component status as the ISL62881CHRTZ is listed as discontinued by Renesas Electronics Corporation. Confirm availability of alternative packages or successor models through official distributors. Ensure compliance with RoHS3 specifications and check moisture sensitivity level (MSL 3) handling requirements during assembly.

Special Purpose Regulators Selection Notes

Select this component for applications requiring a compact, single-phase solution for IMVP-6.5 compliant processors. Consider the 28-TQFN package size constraints and thermal performance. Verify that the 7V to 40V input range aligns with the system's power rail capabilities and that the 0.013V to 1.5V output range covers the target processor's voltage requirements.

Special Purpose Regulators Part Context

The ISL62881CHRTZ belongs to the ISL6288x series of voltage regulators developed by Renesas (formerly Intersil). This series targets high-performance mobile computing platforms, providing robust power management for central processing units and graphics processors in laptops and tablets.

Special Purpose Regulators Replacement Considerations

As the ISL62881CHRTZ is discontinued, consult Renesas documentation for officially confirmed substitute part numbers. Evaluate pin-compatible alternatives within the same IMVP-6.5 family or newer generations that maintain similar electrical characteristics and package dimensions.
