TLV431AFTA Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for TLV431AFTA is -40°C to 125°C.
  • To ensure stability, it's recommended to decouple the input pin with a 10nF to 100nF capacitor and use a low-ESR capacitor (e.g., ceramic or film capacitor) for the output capacitor.
  • The maximum output current that TLV431AFTA can provide is 15mA.
  • While TLV431AFTA can be used as a voltage regulator, it's not recommended as it's primarily designed as a voltage reference. For voltage regulation, consider using a dedicated voltage regulator IC.
  • The output voltage of TLV431AFTA can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistor connected between the output and the adjust pin, and R2 is the resistor connected between the adjust pin and ground.
