TL431QD Frequently Asked Questions (FAQ)

  • The TL431QD can operate from -40°C to 125°C, but the accuracy and stability of the output voltage may degrade at extreme temperatures.

  • While the TL431QD can handle up to 100 mA of output current, it's not suitable for high-current applications due to its limited power dissipation and thermal resistance. For high-current applications, consider using a dedicated voltage regulator IC.

  • To ensure stability, use a minimum output capacitance of 10 nF, and consider adding a series resistor (e.g., 10 Ω) between the output and the load to prevent oscillations. Additionally, ensure that the input voltage is well-regulated and decoupled.

  • While the TL431QD has a relatively low output voltage tolerance (±1%), it may not be suitable for high-precision applications due to its temperature coefficient and noise sensitivity. Consider using a dedicated precision voltage reference IC for such applications.

  • The output voltage (Vout) can be calculated using the formula: Vout = 2.5V x (1 + R1/R2), where R1 and R2 are the resistors in the external divider. Ensure that the resistors are of high precision and low temperature coefficient to maintain accuracy.
