LM2990T-15 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2990T-15 is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR of 0.1-10 ohms is recommended. Additionally, the input capacitor should be at least 1uF with an ESR of 0.1-10 ohms.
  • The LM2990T-15 can provide up to 3A of output current, but it's recommended to derate the output current based on the ambient temperature and input voltage.
  • To protect the LM2990T-15 from overheating, ensure good thermal conductivity between the device and the heat sink, and provide adequate airflow. The thermal shutdown feature will also help protect the device from overheating.
  • The LM2990T-15 is rated for operation up to 125°C, but the output current should be derated based on the ambient temperature. Consult the datasheet for more information on thermal derating.
