LM431AIZ/NOPB Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LM431AIZ/NOPB is -40°C to 125°C.
  • To ensure stability, a 10nF to 100nF capacitor should be connected between the output pin and ground, and the device should be operated within the recommended operating conditions.
  • The maximum allowed voltage on the cathode pin is 36.5V, exceeding which may cause damage to the device.
  • No, the LM431AIZ/NOPB is a voltage reference device, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage.
  • To minimize noise and oscillations, use a low-ESR capacitor (e.g., ceramic or film capacitor) for decoupling, keep the device away from high-current or high-voltage lines, and use a well-regulated power supply.
