> Are there any voltage regulators around that are better than

"better" is a very broad term. There are many factors to consider

Source voltage and current
Terminal voltage and current
Drop-out
Quiescent current
Size
Cost

The question is probably best answered by having an actual
application

For example -

Battery-powered (eg AAA or coin cell). 78L05 probably not
a good choice because of Iq and drop-out. An LP29xx would
be better. More sophisticated regulators also have shut-downs

If you've power to spare, a switcher perhaps. Cuts down on
heat production from wasted drop

etc etc etc. Too many scenarios to keep going with examples
