REF5045AIDR 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 and accuracy over temperature, it's essential to follow proper PCB layout and thermal management practices, and to use a stable input voltage and decoupling capacitors.
  • No, the REF5045AIDR is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
  • The maximum input voltage for the REF5045AIDR is 12V, but it's recommended to operate it within the specified input voltage range of 4.5V to 11V for optimal performance.
  • To minimize noise and ripple, use a low-ESR output capacitor, ensure good PCB layout and grounding, and consider adding a noise-reducing capacitor in parallel with the output capacitor.
