I hope this isn't too dumb a question.
I have an IC that requires a +5 and -5 volt supply. My method would be to use a centre tapped 12v transformer, two rectifiers, a7805 and a 7905 and a handful of capacitors in there somewhere. Is there a tidier method of getting this, maybe a voltage regulator designed for the job?
Guessing that this might be called a symmetrical power supply my googling has found this
