TL431ACD Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431ACD is -40°C to 125°C.
  • To ensure stability, it's recommended to use a bypass capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to keep the impedance of the output circuit low.
  • The maximum allowed voltage on the REF pin is 36V, but it's recommended to keep it below 30V to ensure reliable operation.
  • While the TL431ACD can be used as a voltage regulator, it's not recommended due to its limited current capability (typically 100mA). Instead, use it as a voltage reference and pair it with an external pass transistor or voltage regulator IC.
  • The output voltage of the TL431ACD can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the internal reference voltage (2.5V), and R1 and R2 are the resistors in the voltage divider network.
