It sets a stable reference voltage between 1.24 V and 6 V using two external resistors, with a ±0.5% tolerance.
The output adjusts from 1.24 V up to 6 V via a resistor divider from the cathode to the reference pin. 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. Surface-mount only.
Yes, the TS431BILT is a drop-in functional replacement for the TL431 in most circuits. 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.
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. For extended-temperature designs, the TS431BILT remains the correct choice.
