I know that the LM138/LM338 regulator family is rated for 5 Amperes output current.sgt. thanks for your response to my post. 338 are 5 amp.
I am afraid that you are mistaken, as the maximum rating for the LM317K (TO3 package) is 1.5 Amperes. Please look at the datasheet. (Note that National Semiconductor's datasheet was recently updated, please visit their website and download a copy of the LM117/LM317 datasheet)will be using 2 317k, 3 amp ea.
You will have a very hard time with power dissipation in the regulators.input voltage is 33 volts.
output, 1.2-30 v. 20 amps. (well heatsunk)
The first question you need to ponder is why do you believe that such high current over such a wide voltage range is necessary?i have several diagrams of the circuits. however, some diagrams show the voltage reg. output going to the adj. of the current
reg. i don't think this is what i need. what is the best way
to hook the two reg. together
