LM3509SD/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3509SD is 18V. Exceeding this voltage may damage the device.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be placed as close to the output pin as possible.
  • The maximum output current that the LM3509SD can deliver is 3A. Exceeding this current may cause the device to overheat or shut down.
  • To protect the LM3509SD from overheating, ensure good thermal conductivity between the device and the PCB, and provide adequate airflow around the device. A heat sink may be required for high-power applications.
  • The LM3509SD is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly cooled and derate the output current accordingly.
