Voltage Reference Procurement Notes

Verify the specific suffix DQ1MFR3.0 against official Texas Instruments documentation to confirm the exact output voltage tolerance and package variant. Ensure compatibility with AEC-Q100 requirements if used in automotive designs. Cross-reference ordering information directly with manufacturer datasheets to avoid discrepancies in revision levels or packaging specifications.

Voltage Reference Selection Notes

Select this component when a fixed 3.0 V reference with high precision is required in space-constrained automotive or industrial designs. The SOT-23-5 package offers a small footprint compared to larger alternatives. Consider the 20 ppm/°C temperature coefficient for applications where thermal stability is critical. Verify that the 20 mA shunt current capability meets the load requirements of the target circuit design.

Voltage Reference Part Context
