REF3212AMDBVREP datasheet by Texas Instruments

REF3212AMDBVREP Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the REF3212?
  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 REF3212 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 thermal hysteresis of the REF3212?
  The thermal hysteresis of the REF3212 is typically around 1-2mV, which means the output voltage may vary slightly when the device is cycled through temperature changes.
• Can I use the REF3212 as a voltage regulator?
  No, the REF3212 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 REF3212 away from noisy components, use a solid ground plane, and keep the output traces short and direct to minimize noise and ensure accurate voltage reference.
