REF5025AIDG4 datasheet by Texas Instruments

REF5025AIDG4 Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF5025?
  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 REF5025 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 current below 10mA.
• What is the temperature range for the REF5025?
  The REF5025 is specified to operate from -40°C to 125°C, but the accuracy and stability may degrade at extreme temperatures.
• Can I use the REF5025 as a voltage regulator?
  No, the REF5025 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage.
• How do I layout the PCB to minimize noise and ensure accurate voltage reference?
  Keep the REF5025 away from noisy components, use a solid ground plane, and keep the input and output traces short and separate to minimize noise coupling.
