TL431AIYDT ST Voltage References

The TL431AIYDT is an AEC-Q100 qualified automotive-grade adjustable shunt voltage reference from STMicroelectronics in an 8-pin SOIC package . For selection, verify the output voltage can be set from 2.495V to 36V using two external resistors, confirm sink current capability from 1mA to 100mA, note typical output impedance of 0.22Ω, and ensure automotive temperature range from -40°C to +125°C with 1% or 2% voltage precision options . Features include excellent thermal stability, low dynamic output impedance, and qualification for automotive applications. Ideal for power supply feedback circuits (opto-coupler drivers), precision voltage references for ADCs/DACs, shunt regulators replacing zener diodes, overvoltage protection circuits, constant current sources, and industrial control systems in automotive and power management applications .
