I need to design a regulated power supply that will supply 1 A output current with a DC voltage output of +5V and -12V with a ripple voltage of 0.01 V peak to peak.

Could any experts here help me?
I appreciate if experts could simply give some draftly circuit guide on this design.
The design should provide output short circuit protection.

Thanks

Cheers, Carestaly

+5V can be generated by LM7805 voltage regulator and -12V by LM7912 negative voltage regulator ..
Use 230V/2x15V transformer (CT) and connect everything as shown on the attached picture ..
