Procurement Notes
Verify the specific suffix 'PKG3' against the official Texas Instruments datasheet to confirm the exact package type and environmental compliance status. Ensure that the sourcing channel provides valid traceability documentation for this discontinued or end-of-life product variant. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components during procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for precision shunt regulation applications. Consider the 1% initial accuracy and 92 ppm/°C temperature coefficient for circuit stability requirements. Verify that the SOT-89-3 package dimensions fit the available PCB space and that the thermal performance meets the design constraints for the intended operating environment.
Part Context
This component belongs to the TL431 family of adjustable precision shunt regulators from Texas Instruments. These devices are widely used as voltage references in power management applications. The TL431 series offers a cost-effective alternative to Zener diodes with superior accuracy and temperature stability characteristics suitable for industrial and consumer electronics.
Replacement Considerations
Consult the official Texas Instruments replacement guide for verified substitutes. Check for pin-compatible alternatives with matching electrical specifications if direct sourcing is unavailable.
