Additional Information

This LM338T voltage regulator chip (aka LM338) works in exactly the same way as the LM317T voltage regulator, the only difference being it can deal with higher currents.

The LM338T is rated at 5 Amps continuous current and short bursts (50 milliseconds) of up to 7 Amps. Used with a suitable heatsink the LM338 will manage continuous currents of up to 8+ Amps.

The LM338T is commonly used in solar battery chargers and to provide a 5 Amp fixed voltage power supply from a higher voltage battery bank.

The output voltage is set using two resistors. If you require resistors please contact us with details of your exact requirements and we will assist you.

Heatsink

TO220 Bolt on Heatsink for LM317T

Click here to purchase a TO220 Bolt-On Heatsink suitable for use with the LM338T. This will keep the temperature of the LM338T down when used to provide currents close to the rated value or when there is a large difference between the input voltage and the chosen output voltage.
