LM431ACM3X Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LM431ACM3X is -40°C to 125°C.
  • To ensure stability, it is recommended to decouple the input pin (K) with a 10nF to 100nF capacitor and to use a low-ESR capacitor (e.g., ceramic or film capacitor) for the output capacitor (Cout).
  • The maximum allowed voltage on the cathode (K) pin is 36V.
  • No, the LM431ACM3X is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the current-handling capability of a voltage regulator.
  • The output voltage of the LM431ACM3X is determined by the ratio of the resistors R1 and R2, according to the formula: Vout = 2.5V x (R1 + R2) / R2.
