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.
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.
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.

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.
