TL431AIDMR2G Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431AIDMR2G is -40°C to 125°C.
  • To ensure stability and prevent oscillation, it's essential to follow proper PCB layout guidelines, use a low-ESR capacitor, and decouple the device with a 10nF to 100nF capacitor.
  • The maximum allowed voltage on the REF pin is 2.5V. Exceeding this voltage may damage the device.
  • While the TL431AIDMR2G can be used as a voltage regulator, it's not recommended due to its limited current capability (25mA). Instead, use it as a voltage reference or shunt regulator.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.495V), and R1 and R2 are the external resistors.
