I am looking for a voltage regulator with dual 5v and 15v fixed voltage outputs. The regulator has got to be a stepdown regulator with a max input voltage that is at least 35V dc.
Any help will be much appreciated.

 

This going to be a project, because your won't find a single regulator to do this.

A computer power supply has ±5 and ±12, though the currents are assymetrical.

What are the currents you're wanting?

 

I am looking for less than 1A dc current. Previously I used the LM2575HVT-5.0 and the LM2575HVT-15.0 to provide the 5V and 15V respectively, but I am now wondering whether there is a single chip (with two output pins) which can provide these voltages.
