ADR431ARZ 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 ADR431ARZ can supply up to 10mA of output current, but it's recommended to keep the output current below 5mA for optimal performance and stability.
  • The ADR431ARZ has a soft-start feature that prevents output voltage overshoot during power-up. During power-down, the output voltage decays slowly to prevent any voltage spikes.
  • The ADR431ARZ is specified to operate from -40°C to 125°C, making it suitable for high-temperature applications. However, the output voltage may drift slightly with temperature changes.
