TL431IZ-AP Frequently Asked Questions (FAQs)

  • The TL431IZ-AP can operate from -40°C to 150°C, but the accuracy and stability of the output voltage may degrade at extreme temperatures.
  • To ensure stability, a minimum load current of 1mA is recommended, and a capacitor of at least 100nF should be connected between the output and ground pins to filter out noise and oscillations.
  • Yes, the TL431IZ-AP can be used as a voltage reference, but its output voltage may have a higher temperature coefficient than a dedicated voltage reference IC. Additionally, the output voltage may be affected by the load current and output capacitance.
  • The output voltage of the TL431IZ-AP can be calculated using the formula: Vout = 2.5V x (R1 + R2) / R2, where R1 and R2 are the resistors in the resistive divider.
  • The TL431IZ-AP is a commercial-grade device and may not meet the requirements for high-reliability applications. STMicroelectronics offers other versions of the TL431 with enhanced reliability and quality control for such applications.
