Hi,
I'm looking for a regulator circuit which can take a 12 to 15 volts coming from a bridge after a transformer and has 2 output for 3v and 5v.
Thank you in advance
 

Simplest solution: use 7805 and 7803 regulators... but...

You have not said how much current you require, or how good the regulation and noise figures need to be.
 
As FoxyRick mentioned you can use separate voltage regulator for 3V and 5V. Can be very small in SMD such as SOT-23 case.

If you use linear regulator take in consideration that regulator dissipate power between 12V-15V of input voltage and voltage of regulator x current. In any case you will have heated part.

What with current needs, you didnt mention nothing about that?
