REF3133AIDBZR 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 follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and avoid long output traces that can cause oscillations.
  • The maximum input voltage is 18V, but it's recommended to operate the device within the specified operating range of 4.5V to 16V for optimal performance.
  • No, the REF3133 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
  • The REF3133 has a typical output voltage accuracy of ±0.5% at 25°C, but this can vary depending on the specific device and operating conditions.
