TL431AIDG4 datasheet by Texas Instruments

TL431AIDG4 Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the TL431AIDG4?
  The recommended operating temperature range for the TL431AIDG4 is -40°C to 125°C.
• How do I ensure stability when using the TL431AIDG4 as a voltage reference?
  To ensure stability, it is 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 TL431AIDG4 can supply?
  The TL431AIDG4 can supply up to 15mA of output current, but it is recommended to limit the output current to 10mA or less to ensure stability and accuracy.
• Can I use the TL431AIDG4 as a voltage regulator?
  While the TL431AIDG4 can be used as a voltage regulator, it is not recommended as it is not designed for high-current applications. Instead, use a dedicated voltage regulator IC for high-current applications.
• How do I adjust the output voltage of the TL431AIDG4?
  The output voltage of the TL431AIDG4 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.
