TL431BCDR Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for TL431BCDR 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 in the output filter capacitor.
  • Yes, TL431BCDR is suitable for high-temperature environments, but its voltage reference accuracy may degrade at temperatures above 100°C.
  • The maximum allowed voltage on the cathode (K) pin is 36V, but it's recommended to keep it below 30V for reliable operation.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the internal reference voltage (2.5V) and R1 and R2 are the resistors in the voltage divider network.
