LM338T/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM338T is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.
  • The maximum current that the LM338T can supply is 5A. However, the device can be paralleled to increase the output current.
  • To protect the LM338T from overheating, ensure good heat sinking, and keep the junction temperature (TJ) below 125°C. A heat sink with a thermal resistance of less than 10°C/W is recommended.
  • No, the LM338T is a linear voltage regulator and is not designed for use in switching regulator applications. It is intended for use in linear regulator applications only.
