TL431CZT Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431CZT is -40°C to 125°C.
  • To ensure stability, a minimum capacitance of 100nF should be connected between the REF and ADJ pins, and the device should be decoupled from the power supply with a 10uF capacitor.
  • The maximum allowed voltage on the REF pin is 36V, and it is recommended to keep it below 30V for reliable operation.
  • Yes, the TL431CZT can be used as a voltage regulator, but it is not designed for high-current applications. It is suitable for low-current, low-dropout voltage regulation.
  • The output voltage of the TL431CZT can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistance between the OUT and ADJ pins, and R2 is the resistance between the ADJ and GND pins.
