TL431CP Frequently Asked Questions (FAQ)

  • The TL431CP 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, use a minimum output capacitance of 100nF, keep the output voltage below 36V, and avoid using long output wires or traces that can cause oscillations.

  • The TL431CP can operate with an input voltage as low as 2.5V, but the output voltage accuracy may degrade below 3V.

  • While the TL431CP can be used as a voltage regulator, it's not recommended due to its limited current capability (up to 100mA) and lack of short-circuit protection. Instead, use it as a voltage reference and pair it with an external pass transistor or regulator for higher current applications.

  • The output voltage of the TL431CP is determined by the ratio of the resistors R1 and R2, and the internal reference voltage (2.495V). Use the formula: Vout = 2.495V x (1 + R2/R1) to calculate the output voltage.
