Voltage Reference Procurement Notes

Verify the specific suffix 'QCIM3' against the official datasheet to confirm the 2.048V output and 0.5% tolerance. Ensure the component meets AEC-Q100 requirements if used in automotive designs. Check for RoHS compliance status as indicated in the latest manufacturer documentation before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when a stable 2.048V reference is required in space-constrained automotive or industrial environments. The SOT-23-3 package offers a small footprint suitable for dense PCB layouts. Consider the 50 PPM/°C temperature coefficient for thermal stability needs and verify that the 15 mA maximum current rating aligns with the circuit's load requirements.

Voltage Reference Part Context

This part belongs to the LM4050-N series of micro-power shunt voltage references. The family includes various fixed voltage options and accuracy grades. The 'Q' designation indicates automotive qualification, while 'CIM3' specifies the specific voltage and tolerance variant within the SOT-23-3 package lineup.

Voltage Reference Replacement Considerations

LM4050QBIM3X2.0/NOPB: Offers higher 0.2% accuracy but may have different thermal characteristics. LM4050CEM3X2.0/NOPB: Commercial grade version without AEC-Q100 qualification. Verify pinout compatibility and electrical parameter overlaps before substitution.
