LM338K Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM338K is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be located close to the device. Additionally, the input capacitor should be at least 10uF to prevent oscillations.
  • The maximum output current that the LM338K can deliver is 5A. However, the device can deliver up to 7A for short periods of time, but this may reduce its lifespan.
  • To protect the LM338K from overheating, ensure good heat sinking, and keep the device away from high-temperature sources. The device has a built-in thermal shutdown that turns off the output when the junction temperature exceeds 150°C.
  • No, the LM338K is a linear voltage regulator and is not suitable for switching regulator applications. It is designed to provide a stable output voltage in linear regulator circuits.
