LM3489QMMX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output voltage within the recommended range of 1.2V to 15V.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • To reduce noise and ripple, use a low-ESR output capacitor, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific application and operating conditions.
