Problems with lm338k

[edwinvarghese]

The opamp distributes the load equally to the three LM338 regulators. You can add a PNP emitter-follower transistor like a TIP32 to the output of the opamp inside its negative feedback loop, then many regulators can be used.

only need to add that transistor to the circuit and can i connect the next regulator parallel is ther any other modification that i have to do???

And can you help me with that schematic??? please sir??

I modified the schematic so it can supply 20A to burn out your cheap Chinese servo. I do not like HobbyKing products.

Don't say so its my bachelor's main project Demonstration is day after tomorrow m working hard on it.......

so it can supply 20A to burn out your cheap Chinese servo

You are kidding right? It only works when m giving a output of LM338K regulator in parallel with the 15A ....

But anyway Thanks a lot sir


Rating of new 1K is same right????

Also is there any replacements for TIP32 ??? In case if i dint got it here (as i mentioned here its bit hard to get components )

Sir thanks for all the help one last question, how that op amp TL081 works as an load distributor can you illustrate its working????
