TL431BCLPR Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for TL431BCLPR is -40°C to 125°C.
  • To ensure stability, it's recommended to use a minimum output capacitance of 10uF, and to place the capacitor close to the TL431BCLPR. Additionally, a series resistor (Rs) should be used to limit the current into the capacitor.
  • The maximum allowed voltage on the REF pin is 36V. Exceeding this voltage can damage the device.
  • Yes, TL431BCLPR is suitable for high-temperature environments. However, the voltage reference accuracy may degrade at high temperatures. It's recommended to use a voltage reference with a tighter tolerance if high accuracy is required.
  • The output voltage (Vout) 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.
