LM338 0-5A adjustable current source

adjustable current source

Is it possible to design a constant current source adjustable from 0 to 5A using a LM338K (TO-3 case) voltage regulator with a single potenciometer?

Regards,

Fernando

Use the schematic for Precision Current limiter given in the datasheet. But the pot will be a low value, something not easy to find.

and also it will depend on the amount of voltage you will used...

have you found out your problem? i have to solve the 0-5A adjustable current problem.
