Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to ordering. Ensure that the SOT-23-5 footprint matches the target PCB design. Check for any obsolescence notices or lifecycle changes that may affect long-term supply stability.
Selection Notes
Select this component when precise voltage referencing is required in compact surface-mount designs. The ±0.5% tolerance suits applications demanding higher accuracy than standard shunt regulators. Consider the 100 mA current rating for load requirements and ensure the thermal environment stays within the specified operational temperature range for reliable performance.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but offers specific package and performance variations tailored for modern surface-mount electronics. The device serves as a fundamental building block for voltage reference and regulation in various power management ICs.
Replacement Considerations
Direct substitutes include the TL431BIDBVR. Cross-reference specifications for pinout compatibility and electrical parameters before substitution.
