REF02AU/2K5 Frequently Asked Questions (FAQs)

  • The recommended input voltage range for the REF02AU/2K5 is 4.5V to 36V. Operating the device outside of this range may affect its performance and accuracy.
  • To ensure stability and accuracy, it's essential to decouple the input voltage with a 1uF to 10uF capacitor, and use a low-ESR capacitor (e.g., ceramic or film capacitor) for the output capacitor. Additionally, keep the device away from high-current or high-frequency circuits to minimize noise and interference.
  • The typical output impedance of the REF02AU/2K5 is around 0.2 ohms. This low output impedance ensures that the device can drive moderate loads without significant voltage drop.
  • No, the REF02AU/2K5 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it's not intended to regulate voltage or provide a high current output.
  • The REF02AU/2K5 has a temperature coefficient of ±10 ppm/°C, which means its output voltage may vary slightly with temperature changes. However, the device is designed to maintain its accuracy over a wide temperature range (-40°C to 125°C).
