TL431CD Frequently Asked Questions (FAQ)

  • The TL431CD can operate from -40°C to 125°C, but the accuracy and stability of the voltage reference may degrade at extreme temperatures.

  • To ensure stability, it's essential to decouple the TL431CD with a 10nF to 100nF capacitor between the REF and ADJ pins, and a 1μF to 10μF capacitor between the VIN and GND pins.

  • The TL431CD can operate with an input voltage as low as 2.5V, but the output voltage accuracy may degrade below 3.5V.

  • While the TL431CD can be used as a voltage regulator, it's not recommended due to its limited current sourcing capability (typically 10mA). Instead, use it as a voltage reference and pair it with an external amplifier or transistor for voltage regulation.

  • The output voltage (VOUT) can be calculated using the formula: VOUT = 2.495V x (1 + (R1 / R2)), where R1 and R2 are the resistors connected between the REF, ADJ, and GND pins.
