Special Purpose Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration against official Renesas documentation. Confirm RoHS compliance status as datasheets may vary by revision. Check current lifecycle status as this series has been subject to discontinuation notices. Ensure the 40-QFN package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when designing three-phase buck converter topologies for high-performance CPUs requiring integrated gate drive capabilities. The fixed input range suits standard bus voltages, while the adjustable output covers typical core voltage needs. Consider the thermal performance of the QFN package for heat dissipation in dense layouts. Verify compatibility with the specific VID code set required by the target processor architecture.
