TL431CD Frequently Asked Questions (FAQs)

  • The minimum operating voltage for TL431CD is 2.5V, but it's recommended to operate it at 4.5V or higher for stable operation.
  • To ensure stability, make sure to decouple the TL431CD with a capacitor (typically 10nF to 100nF) between the REF and ADJ pins, and use a low-ESR capacitor (typically 1uF to 10uF) between the output and GND pins.
  • The maximum current that TL431CD can handle is 100mA, but it's recommended to operate it at 50mA or less for reliable operation and to prevent overheating.
  • Yes, TL431CD can be used as a voltage reference for an ADC, but it's essential to ensure that the TL431CD is properly decoupled and that the output voltage is stable and noise-free.
  • The output voltage of TL431CD can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.495V), R1 is the resistance between the ADJ and OUT pins, and R2 is the resistance between the ADJ and GND pins.
