Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status as required by local regulations. Ensure proper ESD handling procedures are followed during storage and assembly. Check datasheet revisions for any updates regarding pin configurations or electrical characteristics before finalizing design integration.

Selection Notes

Select this part when a 5.0V reference with 0.5% accuracy is required in small packages. Consider the SC70-5 form factor for tight board layouts. Evaluate operating current requirements against the 60µA minimum threshold. Verify thermal management needs given the package size and power dissipation limits under varying ambient conditions.

Part Context

This component belongs to the LM4040 family of bandgap voltage references. It serves as a cost-effective alternative to other precision references while maintaining high accuracy. The H5 suffix indicates the specific SC70-5 package variant, which is noted as End of Life in official documentation.

Replacement Considerations

Official documentation lists SC70-5 variants as End of Life. Consider upgrading to SOT23 package versions such as LM4040C50FTA for continued production availability. Verify pin compatibility and electrical specifications match before substituting.
