Procurement Notes

Verify component status carefully as this part may be obsolete or no longer manufactured. Confirm environmental compliance such as ROHS and REACH directives if required for your specific application standards. Check for potential tariff implications when shipping to certain regions like the United States. Ensure the supplier provides valid traceability documentation for legacy components.

Selection Notes

Select this component only if designing for DDR SDRAM termination where its specific input voltage range of 1.6V to 3.6V matches the system requirements. Consider the SPAK-5 surface mount package constraints during PCB layout. Evaluate whether the integrated termination solution sufficiently reduces board space compared to discrete resistor networks.

Part Context

This component belongs to NXP's special purpose regulators family, specifically tailored for memory interface power management. It serves as a dedicated solution for DDR technologies, replacing multiple discrete components. The product line focuses on simplifying design complexity for high-speed memory applications through integrated power conversion and termination features.

Replacement Considerations

Check for direct substitutes from NXP or other manufacturers offering compatible DDR termination regulators. Verify pin compatibility and electrical specifications before substitution. Note that alternative packages may require schematic and layout modifications.
