REF3333AIDBZT Frequently Asked Questions (FAQs)

  • The typical output voltage tolerance of the REF3333 is ±0.05% (±3.33 mV) at 25°C.
  • To ensure stability and accuracy, decouple the input pin (VIN) with a 10-µF capacitor, and use a 10-Ω resistor in series with the output pin (VOUT) to prevent oscillations.
  • The recommended input voltage range for the REF3333 is 4.5 V to 18 V, with a minimum input voltage of 4.5 V for proper operation.
  • The REF3333's output voltage has a temperature coefficient of ±10 ppm/°C, which means the output voltage will change by ±10 ppm (parts per million) for every 1°C change in temperature.
  • No, the REF3333 is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, not to regulate voltage.
