It’s basically a privately hosted repo with a very small set of programs/libraries. PPA is a Personal Package Archive.
If you run Ubuntu (or most Debian derivatives) you can add a PPA as an extra repo and the version of software in that repo will usually be newer than the versions maintained by the distro (or even not present in the distro).
It’s not quite like the AUR - the AUR is a central public repo that people submit their packages to. Each PPA is a privately run and maintained repo with their packages in.
It is used by some projects to officially distribute their software but it is also something of a potential security nightmare.
