REF3020AIDBZT Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF3020?
  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 REF3020 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 REF3020 can handle?
  The REF3020 can handle input voltages up to 18V, but it's recommended to operate within the specified range of 4.5V to 16V for optimal performance.
• Can I use the REF3020 in a high-temperature environment?
  The REF3020 is rated for operation up to 125°C, but its accuracy and stability may degrade at higher temperatures. It's recommended to derate the device's performance at elevated temperatures.
• How do I minimize noise and ripple on the REF3020 output?
  To minimize noise and ripple, use a low-pass filter on the output, such as a 1kΩ resistor and a 10uF capacitor, and ensure good power supply decoupling and PCB layout practices.
