• Portable battery-powered devices

Voltage Reference Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 qualification and 'C' denotes the 0.5% accuracy grade. Confirm the 'ADJ' designation matches the requirement for variable output settings rather than fixed voltage options. Ensure the 'SOT-23-3' package aligns with PCB layout constraints. Cross-reference the manufacturer part number against official Texas Instruments documentation to confirm availability status and revision history before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when automotive reliability certification is mandatory alongside precise voltage referencing in compact designs. The adjustable feature allows flexibility in setting reference levels between 1.225V and 10V. Consider the 150 ppm/C temperature coefficient for thermal stability requirements. The SOT-23-3 package is suitable for space-constrained surface-mount assemblies. Evaluate the 12 mA maximum current capability against load demands.
