Special Purpose Regulators Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is currently restricted or unavailable in many regions. Verify current stock status and lead times through authorized distributors before design finalization. Consider obsolescence impact on long-term supply chain stability.

Special Purpose Regulators Selection Notes

Select this part only if legacy compatibility with Intel VRD/VRM standards is required. Ensure the TSSOP-28 package fits the target PCB layout constraints. Evaluate thermal performance within the specified 0°C to +85°C operating range. Confirm that the 837.5 mV to 1.6 V output range meets system voltage requirements.

Special Purpose Regulators Part Context

Part of the ADP3190 series, this controller targets high-performance computing power supplies. It complements other onsemi PMIC solutions like the ADP3192 and ADP3193. These components share similar architectural goals but differ in output counts and package types. The series focuses on stable voltage regulation for processor loads.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the End-of-Life status. Designers should consult official replacement guides or contact onsemi directly for qualified alternatives.
