Look at the huge difference of their thermal resistance. The TO-3 case can dissipate much more heat than the TO-220 case.whiz115 said:what's the difference between LM350 in TO-3 and TO-220 packages? i don't see any difference other than that the first is case mounting component.

audioguru said:The LM350 has a current of 3.0A only if its input to output voltage is at or less than 10V. With 30V from input to output the current is only 250mA.
No.whiz115 said:yeah but with a good heatsink it would be fine the TO-220 package right?
No.i mean i can output 3A if of course the voltage difference is less than 10V?
No.the same goes for LM317??? outputs less than 1,5A if the voltage is higher than 10V?)
