TL431ACZ Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the TL431ACZ is -40°C to 125°C.

  • Yes, the TL431ACZ can be used as a voltage regulator, but it's primarily designed as a programmable shunt regulator. It's not suitable for high-current applications.

  • The resistor values depend on the desired output voltage and the reference voltage. A good starting point is to use the equations provided in the datasheet to calculate the resistor values. You can also use online calculators or simulation tools to help with the design.

  • The maximum current that the TL431ACZ can handle is 100 mA. Exceeding this current may cause the device to overheat or malfunction.

  • The TL431ACZ is not suitable for high-frequency applications. It's designed for low-frequency, low-power applications. If you need a high-frequency voltage reference, consider using a different device.
