TL431BQDBZTG4 Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the TL431BQDBZTG4 is -40°C to 125°C.
  • To ensure stability, a minimum capacitance of 100 nF between the REF and ADJ pins is recommended. Additionally, a low-ESR capacitor (e.g., ceramic or film capacitor) should be used to minimize oscillations.
  • The maximum allowed voltage on the REF pin is 36 V. Exceeding this voltage may damage the device.
  • Yes, the TL431BQDBZTG4 can be used as a voltage regulator. However, it is primarily designed as a shunt regulator, and its output current capability is limited to 100 mA.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref * (1 + R1/R2), where Vref is the reference voltage (2.5 V), and R1 and R2 are the resistors connected between the ADJ and REF pins.
