L4931CD120-TR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 30V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and a minimum input capacitance of 1uF with an ESR of less than 5 ohms.
  • The maximum output current is 1.2A, but it's recommended to keep it below 1A for reliable operation and to prevent overheating.
  • Use a heat sink with a thermal resistance of less than 20°C/W, and ensure good airflow around the device. Also, keep the ambient temperature below 70°C.
  • The L4931CD120-TR is rated for operation up to 150°C, but the maximum junction temperature is 125°C. Derate the output current and input voltage to ensure reliable operation at high temperatures.
