Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer as Nuvoton Technology Corporation, noting historical brand transitions from Winbond. Ensure the part status is checked against official notices, as this series may be subject to discontinuation or product change notifications. Cross-reference the 8-SOIC package dimensions with the latest datasheet to guarantee mechanical compatibility during procurement.

Selection Notes

Select this component for designs requiring a dedicated linear bus termination regulator for DDR memory interfaces. The 1.8A output rating supports standard DDR bus loads. Verify that the 8-SOIC package fits the PCB footprint constraints. Consider the thermal performance requirements given the linear topology and the specified operating temperature range of 0°C to 70°C for industrial applications.

Part Context

This component belongs to the W83310 series of bus termination regulators. The series includes variants such as W83310DG-A and W83310DS, which share similar functional goals but may differ in package types or specific electrical characteristics. The W83310SG variant specifically denotes the SOIC package with the associated protection features documented for DDR memory termination tasks.
