Hii....
I am using lm338 ic to-220 package used to provide 5v , 1.5 amp output.........i am giving power form my variable power source........nd had mounted one input electrolite cap 1000uf-25V, and and one 0.1uf ceramic cap at input , and providing 100uf - 25v cap at out. ..nd providing 220ohm resistor at ouput to adj pin terminal....and variableof 22k at adj teminal...by varying this pot i can get 5volt.........bt output current is not going more than 1amp........ plz suggest m wt should i change!!!!!! nd using proper heatsink with ic 338....................
