LM338T Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM338T is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output capacitor.
  • The LM338T can regulate properly with a minimum load current of 10mA, but it's recommended to have a minimum load current of 50mA for optimal performance.
  • The LM338T is rated for operation up to 125°C, but its performance may degrade at high temperatures. Use a heat sink and ensure good airflow to keep the junction temperature below 125°C.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to protect the LM338T from voltage surges and spikes.
