REF102BU Frequently Asked Questions (FAQs)

  • The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
  • To ensure stability, make sure to decouple the input voltage with a 10uF to 22uF capacitor, and use a low-ESR output capacitor. Also, keep the PCB layout clean and avoid long traces.
  • The maximum current that can be drawn from the REF102BU is 10mA. Exceeding this limit may affect the accuracy and stability of the voltage reference.
  • The REF102BU has a temperature coefficient of 10ppm/°C, which means its output voltage will change by 10ppm for every 1°C change in temperature. This can affect the overall accuracy of the system.
  • Yes, the REF102BU is suitable for high-reliability and aerospace applications due to its high accuracy, low noise, and radiation-hardened design.
