TL431AS-13 Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431AS-13 is -40°C to 125°C.
  • To ensure stability, it's recommended to decouple the input pin with a 10nF to 100nF capacitor and use a low-ESR capacitor (e.g., ceramic or film capacitor) for the output capacitor.
  • The maximum allowed voltage on the cathode (K) pin is 36V.
  • While the TL431AS-13 can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. For voltage regulation, consider using a dedicated voltage regulator IC.
  • The output voltage of the TL431AS-13 can be calculated using the formula: Vout = 2.5V x (1 + R1/R2), where R1 and R2 are the resistors in the voltage divider network.
