LM120H-12 Frequently Asked Questions (FAQs)

  • The LM120H-12 can handle input voltages up to 30V, but it's recommended to keep the input voltage at least 2V higher than the output voltage to ensure proper regulation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and a minimum input capacitance of 1uF with an ESR of less than 5 ohms.
  • The LM120H-12 can provide up to 1.5A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
  • To protect the LM120H-12 from overheating, ensure good airflow around the device, use a heat sink if necessary, and avoid operating the device at high ambient temperatures or with high input voltages.
  • No, the LM120H-12 is a linear voltage regulator and is not suitable for use in switching regulator applications. It's designed to provide a stable output voltage in linear regulator applications.
