Procurement Notes

Verify the specific suffix 'X' against official Fairchild or ON Semiconductor documentation to confirm tape-and-reel configuration details. Ensure the part number matches current ON Semiconductor naming conventions following the corporate integration. Confirm RoHS compliance status through official datasheets before procurement.

Selection Notes

Select this component when a fixed 5 V reference is required in space-constrained designs. The SOT-23 package offers a small footprint suitable for portable applications. Verify that the 5 V output aligns with system requirements compared to other available reference voltages.

Part Context

This component belongs to the FAN4040 series of voltage references. Fairchild Semiconductor was acquired by ON Semiconductor, which now manages the product line. The part serves as a precision reference element in power management circuits requiring stable voltage levels.

Replacement Considerations

Check ON Semiconductor's official substitution guide for updated part numbers due to naming convention changes. Verify pinout compatibility if replacing with similar SOT-23 voltage references.
