REF3120AIDBZR Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF3120?
  The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
• How do I ensure the REF3120 is stable and doesn't oscillate?
  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.
• What is the maximum input voltage that the REF3120 can handle?
  The maximum input voltage is 18V, but it's recommended to operate the device within the specified operating range of 4.5V to 15V for optimal performance.
• Can I use the REF3120 in a high-temperature environment?
  The REF3120 is rated for operation up to 125°C, but the accuracy and stability may degrade at higher temperatures. It's recommended to derate the device's performance at elevated temperatures.
• How do I calculate the total error budget for the REF3120?
  The total error budget includes the initial accuracy, temperature coefficient, and long-term stability. Calculate the total error budget by adding these components and considering the specific application requirements.
