TL431ASA-7 Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for the TL431ASA-7 is -40°C to 125°C.

  • To ensure stability, a decoupling capacitor of at least 10nF should be connected between the REF and ADJ pins, and the device should be operated within the recommended operating conditions.

  • While the TL431ASA-7 can be used as a voltage regulator, it is not recommended as it is primarily designed as a voltage reference. For voltage regulation, a dedicated voltage regulator IC is recommended.

  • The TL431ASA-7 can sink up to 15mA and source up to 1mA.

  • The output voltage of the TL431ASA-7 can be adjusted by connecting a resistor divider network between the REF and ADJ pins, and adjusting the ratio of the resistors to achieve the desired output voltage.
