The ±0.5% tolerance means the set point stays within half a percent over temperature and load. Supplied in SOT-753, the supplier device package is SOT-23-5.

The TS431BILT offers a tighter ±0.5% tolerance versus the TL431's typical 1% or 2% grades, and its -40°C to 125°C range exceeds the TL431's commercial temperature grade. Pinout and basic operation are identical."},{"question":"What is the closest functional second-source for TS431BILT?","answer":"The TL1431ACL5T is a functional alternative with ±0.25% tolerance and 100 mA output, but its temperature range is -20°C to 70°C — it does not cover the TS431BILT's -40°C to 125°C industrial/automotive grade.
