REF3125AQDBZRQ1 Frequently Asked Questions (FAQs)

  • The typical output impedance of the REF3125 is around 0.5 ohms.
  • To ensure stability, use a 10uF or larger capacitor at the output, and a 1uF or larger capacitor at the input. Also, keep the layout clean and avoid long traces.
  • The recommended input voltage range for the REF3125 is 4.5V to 18V. Operating outside this range may affect performance and accuracy.
  • The REF3125 is rated for operation up to 125°C. However, accuracy and stability may degrade at high temperatures. Consider using a thermally-enhanced package or a different voltage reference for high-temperature applications.
  • Use a low-ESR capacitor (e.g., ceramic or film) at the output, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground. Also, keep the input voltage clean and well-regulated.
