REF3120AIDBZT datasheet by Texas Instruments

REF3120AIDBZT Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF3120AIDBZT?
  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 REF3120AIDBZT is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input voltage with a 10uF capacitor, use a low-ESR output capacitor, and keep the output capacitor close to the device.
• What is the maximum input voltage that the REF3120AIDBZT 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 REF3120AIDBZT in a high-temperature environment?
  The REF3120AIDBZT is rated for operation up to 125°C, but the output voltage may drift with temperature. Consider using a temperature-compensated voltage reference or a more temperature-stable device for high-temperature applications.
• How do I minimize noise and ripple on the output of the REF3120AIDBZT?
  Use a low-pass filter or a pi-filter on the output, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground. Additionally, ensure good PCB layout and decoupling practices.
