Special Purpose Regulators Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and reel quantity. The base part number may correspond to bulk tray packaging while tape-and-reel variants carry distinct suffixes. Confirm RoHS3 compliance status and moisture sensitivity level prior to assembly planning. Check for active production status or end-of-life notifications on official Renesas channels before finalizing procurement.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring strict adherence to Intel VR13 or IMVP8 protocols. Ensure the design accommodates the 48-lead QFN thermal requirements and footprint dimensions. Verify that the host platform supports the required SVID or AVID communication protocols. Consider phase count flexibility if load transient response optimization is critical for the target application.
