• An example screenshot image is very helpful
• Ensure that the associated footprints match the official footprint library
  • A new fitting footprint must be submitted if the library does not yet contain one.
• If there are matching footprint PRs, provide link(s) as appropriate
• Check the output of the Travis automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.

Thanks for contributing and welcome!

1. Can you change 250mA Audio Buffer in the description to Headphone Buffer, 250mA?
2. Then add the package (TO-263) at the end of the description with a comma separator.
3. Pin 3 should be Power Input type.

Done, V- as passive was a vestige of an aborted stacked pin approach, sorry

The changes above are done correctly, but the datasheet should not be in the LIB file, only the DCM file. See the latest commit. Can you fix that and then I can merge?

[qberthet]

Hum, didn't change that, is it because I updated my kicad install to current master since I started the symbol?

Should I edit it by hand?

[evanshultz]

Yes. See http://kicad-pcb.org/libraries/klc/G1.8/. In fact, a more strongly-worded and complete guideline for this clause is under review now.

Ok, thanks, will update my other pull request
