Voltage Reference Procurement Notes

Verify the specific suffix 'DQ1' confirms automotive grade (AEC-Q100) qualification and the '3.0' indicates the 3.0V output variant. Confirm the 'MFT' suffix corresponds to the SOT-23-5 package and tape-and-reel shipping configuration. Ensure compatibility with your system's thermal requirements given the -40°C to +125°C operating range. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate pinout and electrical specifications before integration.

Voltage Reference Selection Notes

Select this component when automotive reliability and high precision are required in a small footprint. The 20ppm/°C temperature coefficient offers superior stability compared to standard industrial references. Consider the 20mA output current capability against your load requirements. The SOT-23-5 package is ideal for space-constrained designs. Evaluate the 5.5V maximum input voltage against your supply rails to ensure proper dropout margin.
