LM809M3-4.38/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 35V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR of 0.1-10 ohms, and a minimum input capacitance of 1uF with an ESR of 0.1-10 ohms.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific device and operating conditions.
  • The LM809M3-4.38/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
  • 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.
