Voltage Reference Procurement Notes

Verify the specific grade suffix 'BI' indicates the B-grade performance specifications and the DC package type against your design requirements. Confirm that the TRMPBF suffix corresponds to the mini tape and reel packaging format required for your assembly process. Ensure compatibility with the specified industrial temperature range and verify lead-free finish compliance if necessary for your manufacturing standards.

Voltage Reference Selection Notes

Select this component when a fixed 1.25V reference with moderate accuracy is sufficient for the application. The B-grade specification offers a balance between cost and performance compared to the higher-precision A-grade options. Consider the DFN package size constraints and ensure adequate thermal management is accounted for during PCB layout. Verify that the load regulation requirements align with the B-grade specifications provided in the datasheet.
