Voltage Reference Procurement Notes

Verify the specific suffix 'AIM3' against official manufacturer documentation to confirm the exact accuracy grade and package variant. Ensure compatibility with existing PCB footprints for the SOT-23-3 form factor. Cross-reference datasheet revisions to validate electrical parameters before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when high precision (0.1%) is required alongside low power consumption in a small footprint. Compare against standard accuracy variants if cost or availability constraints exist. Verify that the 15 mA maximum shunt current meets the circuit's load requirements while maintaining regulation stability.

Voltage Reference Part Context

This part belongs to the LM4050 series of micropower shunt voltage references from Maxim Integrated, now part of Analog Devices. The series offers multiple breakdown voltages and accuracy grades, designed for applications demanding stable reference performance in compact electronic designs.

Voltage Reference Replacement Considerations

LM4050CEM3-2.5+T: Lower accuracy grade (0.5%). LM4050AEX3-2.5+T: Different package (SC-70-3). Verify pinout and thermal characteristics before substitution.
