BD9D321EFJ-E2 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 36V, but it's recommended to keep it below 30V for stable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the ESR (Equivalent Series Resistance) below 1 ohm.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation.
  • Ensure good airflow, use a heat sink if necessary, and keep the junction temperature below 125°C to prevent overheating.
  • Yes, but the output voltage may decrease at high temperatures. Ensure the operating temperature is within the specified range (-40°C to 105°C).
