Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verify end-of-life dates and availability through authorized distributors. Ensure replacement strategies are considered due to discontinued status. Confirm package compatibility and electrical specifications before integration into new designs.

Selection Notes

Select this part only if legacy DDR termination requirements match its 1.46V to 2.5V input range and 3A peak current capability. The 8-SOP-EP package must fit the board layout. Since the part is obsolete, evaluate alternative regulators with similar performance metrics for new projects.

Part Context

The RT9173 series includes variants like RT9173D and RT9173GS, all serving as cost-effective bus termination regulators. These devices address the specific needs of DDR memory interfaces by providing stable termination voltages with high transient response capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, consult manufacturer resources for direct replacements or equivalent functional alternatives.
