LM431ACZ Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LM431ACZ is -40°C to 125°C.
  • Yes, the LM431ACZ can be used as a voltage regulator, but it's primarily designed as a voltage reference. It's not suitable for high-current applications.
  • To ensure stability, use a 0.1 μF to 1 μF capacitor between the Cathode (K) and Anode (A) pins, and a 10 μF to 100 μF capacitor between the Anode (A) and ground.
  • The typical current consumption of the LM431ACZ is around 1.5 mA, but it can vary depending on the operating conditions.
  • While the LM431ACZ can operate up to 125°C, it's not recommended for high-temperature applications. The device's accuracy and stability may degrade above 85°C.
