Supply different voltages using one dual DC supply?

[riie]

Hi all,

I have
- 2 ICs that required +10V and -10V
- 1 ICs that required +5V and -5V

How can I power them up using one dual DC voltage supply?

Thanks!

Search existing EDABoard threads, there is lots of circuits.



Use 7810 7910 7805 7905 voltage regulators instead 7812 7912.

:wink:

What rating is you dual voltage source?

I miss out on that part, it's a variable dual dc supply used in lab.

So just to confirm, I need a 7805 and a 7905 voltage regulator for +5v and -5v respectively?
Are the 2 capacitors for each regulator a must? I know that the capacitor at the output is for stability.
