Procurement Notes
Verify the complete part number including suffixes such as Q1 for automotive grade and DBZT for package type. Confirm that the specific voltage variant matches the design requirement, as the TL4050 series offers multiple fixed output options. Ensure compatibility with the target operating temperature range and packaging format before finalizing procurement.
Selection Notes
Select this component when a stable 2.5 V reference is required in space-constrained automotive or industrial designs. The SOT-23-3 package minimizes board area while maintaining precision. Consider the 15 mA maximum current limit to ensure adequate load regulation without excessive power dissipation in the application circuit.
Part Context
This component belongs to the TL4050 family of precision shunt voltage references from Texas Instruments. The family includes various output voltages and accuracy grades, all sharing similar low-power characteristics. The 'C' designation indicates the 0.5% accuracy tier, while the 'Q' prefix signifies automotive qualification under AEC-Q100 standards.
Replacement Considerations
Direct pin-compatible substitutes within the same family include other TL4050 variants with different voltage outputs. Cross-family replacements may require circuit re-evaluation due to differences in noise performance, current consumption, or package dimensions.
