LM4431M3-2.5/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 1 ohm or less, and a minimum input capacitance of 1uF with an ESR of 1 ohm or less.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for optimal performance and to prevent overheating.
  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific device and operating conditions.
