Negative Voltage generation using regulators

[masab_ahmad]

Hi,

i'm trying to get both positive and negative voltages to run an op amp. will this circuit work? it uses 2 regulators.:

Thanks!

@masab_ahmad: I don't think it works that way.First of all,these devices need an external component—a compensation capacitor at the output.
Why not using two 24V DC batteries connected in series with their mid-point connected to ground,so that you have +24V & -24V & then using 7915

I actually wanted to give + and - 5V to an op amp, and wanted to use 2 small cell phone batteries in series and later regulate the output to the op amps, so the circuit i posted above is not possible?
