LM3489MM Frequently Asked Questions (FAQs)

  • The LM3489MM can handle input voltages up to 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a 10nF capacitor between the VIN and GND pins.
  • The minimum input voltage required for the LM3489MM to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.
  • The LM3489MM is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the LM3489MM can be calculated using the formula: Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
