TL431AQPK Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for TL431AQPK 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 capacitor.
  • The maximum allowed voltage on the REF pin is 6.5V. Exceeding this voltage may damage the device.
  • Yes, TL431AQPK is suitable for high-temperature environments. However, the voltage reference accuracy may degrade at high temperatures.
  • The output voltage can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistor connected between the output and the adjust pin, and R2 is the resistor connected between the adjust pin and ground.
