Also, 78xx and 317/337 regulators are 1.5Amp rated, not 1Amp.


Well in my defense, see pic attached.

And since it's a made up question, so I'll just change the question to 3A  smiley-cool

Here's a 1.5A part (assumption: adequate heatsinking required)

Now, for greater than 1.5Amp (3A, 5Amp), you'll need external power transistors. Their datasheets offer example circuits.
