TL431CDBZR Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431CDBZR is -40°C to 125°C.
  • To ensure stability, it's recommended to use a minimum output capacitance of 10uF and a minimum ESR of 0.1 ohms, and to place the capacitor close to the TL431CDBZR.
  • The maximum allowed voltage on the REF pin is 36V, but it's recommended to keep it below 30V for reliable operation.
  • Yes, the TL431CDBZR is suitable for high-temperature environments, but its accuracy and stability may degrade above 100°C. It's recommended to use a voltage reference with a higher temperature rating if operating above 100°C.
  • The output voltage of the TL431CDBZR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistor connected between the output and the adjust pin, and R2 is the resistor connected between the adjust pin and ground.
