Thanks Again.

How much heat can I expect a LM317 in a TO-220 package dissipate  ?
(w/ and/or w/o heat sink ?)
Below is the link to a Fairchild PDF on the specs, but I don't know calculate the heat ?
Is it just max current ? or do I need to figure the resistance the regulator will have at a particular input to output voltage and current and calculate is as: P=I2R  ?
Any help is appreciated.
Thanks

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.

Miscellaneous

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
