TL431ACLP datasheet by Texas Instruments

TL431ACLP Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for TL431ACLP?
  The recommended operating temperature range for TL431ACLP is -40°C to 125°C.
• How do I ensure stability when using TL431ACLP 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 in the output capacitor.
• Can I use TL431ACLP as a voltage reference in a high-temperature environment?
  Yes, TL431ACLP is suitable for high-temperature environments, but its voltage reference accuracy may degrade at temperatures above 100°C.
• What is the maximum allowed voltage on the cathode (K) pin?
  The maximum allowed voltage on the cathode (K) pin is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I calculate the output voltage of a TL431ACLP-based voltage regulator?
  The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V) and R1 and R2 are the resistors in the voltage divider network.
