TL431BQDBZT Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the TL431BQDBZT?
  The recommended operating temperature range for the TL431BQDBZT is -40°C to 125°C.
• How do I ensure stability when using the TL431BQDBZT in a voltage regulator circuit?
  To ensure stability, it's recommended to use a minimum output capacitance of 10uF and a minimum ESR of 0.1 ohms, and to place the capacitor close to the TL431BQDBZT.
• What is the maximum allowed voltage on the REF pin?
  The maximum allowed voltage on the REF pin is 36V, exceeding which can cause damage to the device.
• Can I use the TL431BQDBZT as a voltage reference in a high-temperature environment?
  Yes, the TL431BQDBZT is suitable for high-temperature environments, but the voltage reference accuracy may degrade at temperatures above 125°C.
• How do I calculate the output voltage of the TL431BQDBZT?
  The output voltage of the TL431BQDBZT can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), R1 is the resistance between the output and the REF pin, and R2 is the resistance between the REF pin and ground.
