LM3405AXMK/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, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, 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 reliable operation and to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
  • The EN (enable) pin is used to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled.
