LM431CIM/NOPB Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LM431CIM/NOPB is -40°C to 125°C.
  • To ensure stability, it is recommended to decouple the input pin (Vref) 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 36.5V.
  • No, the LM431CIM/NOPB is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage.
  • The output voltage of the LM431CIM/NOPB is approximately 2.5V, but it can be adjusted by connecting a resistor divider network between the anode (A) and cathode (K) pins.
