high current voltage regulator?

Is there a version of the LM317 that works up to 10A? How about up to

5A?

Look up the LT1038.

The traditional way to get more than an amp or two with these IC regulators is to use the chip to control a power transistor. I used to have a collection of National Semiconductor app notes on the subject, but it's gone with the flood. Newer power supplies usually use switching regulators for higher efficiency. Have you tried one of the big catalog sites, like newark.com?

** The K version does.

Thanks.

Looks like the LT1038 is obsolete/discontinued.

I'll look into the suggestions from Stephen and Phil

National Semiconductor's datasheet (LM117.pdf) says the LM317K is limited to 1.5A. TO-3 package

Any other vendor produce a 10A version?

** Correction.

Look up the LM338 K.

TO3, 6 to 7 amps.
