TL431AILPR datasheet by Texas Instruments

TL431AILPR Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the TL431AILPR?
  The recommended operating temperature range for the TL431AILPR is -40°C to 125°C.
• How do I ensure stability when using the TL431AILPR in a voltage regulator circuit?
  To ensure stability, it's recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm, and to place the capacitor close to the TL431AILPR.
• Can I use the TL431AILPR as a voltage reference in a high-temperature environment?
  Yes, the TL431AILPR is suitable for high-temperature environments, but it's essential to consider the temperature coefficient of the reference voltage, which is ±2mV/°C.
• What is the maximum allowed voltage on the cathode (K) pin?
  The maximum allowed voltage on the cathode (K) pin is 36V, and it's essential to ensure that the voltage on this pin does not exceed this value to prevent damage to the device.
• How do I calculate the output voltage of the TL431AILPR?
  The output voltage of the TL431AILPR can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the reference voltage (2.5V), and R1 and R2 are the resistors in the voltage divider network.
