TL431ACZT Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the TL431ACZT?
  The recommended operating temperature range for the TL431ACZT is -40°C to 125°C.
• How do I ensure stability when using the TL431ACZT as a voltage reference?
  To ensure stability, it's recommended to use a bypass capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and to keep the impedance of the output circuit low.
• What is the maximum output current that the TL431ACZT can supply?
  The TL431ACZT can supply up to 15mA of output current, but it's recommended to limit the output current to 10mA or less to ensure stability and accuracy.
• Can I use the TL431ACZT as a voltage regulator?
  While the TL431ACZT can be used as a voltage regulator, it's not recommended due to its limited output current capability and lack of built-in overcurrent protection. Instead, consider using a dedicated voltage regulator IC.
• How do I adjust the output voltage of the TL431ACZT?
  The output voltage of the TL431ACZT can be adjusted by connecting a resistor divider network between the REF and ADJ pins, and adjusting the ratio of the resistors to set the desired output voltage.
