LM5085MM/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor's ESR is within the recommended range of 0.1Ω to 10Ω.
  • The maximum output current is 5A, but it's recommended to derate the output current based on the ambient temperature and input voltage.
  • Use a heat sink with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Also, monitor the junction temperature and reduce the output current if it exceeds 125°C.
  • Yes, the LM5085MM/NOPB is qualified for automotive and industrial applications, and meets the requirements of AEC-Q100 and IEC 60747, respectively.
