TL431IL3T Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the TL431IL3T is -40°C to 125°C.

  • 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.

  • The TL431IL3T 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.

  • While the TL431IL3T can be used as a voltage regulator, it's not recommended due to its limited output current capability and lack of built-in current limiting. Instead, consider using a dedicated voltage regulator IC.

  • The output voltage of the TL431IL3T can be adjusted by connecting a resistor divider network between the REF and ADJ pins. The output voltage is determined by the ratio of the resistors and the internal reference voltage (2.5V).
