Procurement Notes
Verify the specific suffix 'LI' against the official Texas Instruments datasheet to confirm it denotes the correct grade or variant intended for your design requirements. Ensure the SOT-23-3 footprint matches your PCB layout constraints. Confirm RoHS compliance status if required by your manufacturing standards before finalizing procurement orders.
Selection Notes
Select this component when a compact SOT-23-3 package is required for space-constrained designs. Choose this part over standard TL431 variants if the specific 'LI' designation aligns with your thermal or accuracy needs. Verify that the 1 mA cathode current requirement fits your biasing circuit design compared to higher current alternatives.
Part Context
This device belongs to the TL431 family of programmable shunt regulators. It serves as a precision voltage reference and control element in feedback loops. The TL431 series is widely used in power management applications due to its reliability and cost-effectiveness. This specific model represents a surface-mount version optimized for automated assembly processes.
Replacement Considerations
The TL431AIDBZR is a manufacturer-recommended alternative within the same family. Verify pin compatibility and electrical parameter alignment before substitution.
