^ You mean that you used an LM7805 and put a bunch of resistors in series AFTER it?
If so, that's not the way to go. I'll tell you a secret many people never mention. You can use an LM7805 for variable or different (than reference 5.0V in this case) like you would an LM317, but when you do, consider the voltage calculation to include 5V reference instead of 1.2V when choosing resistors as seen in the LM317 datasheet example, or see this:

Edit: Come to think of it, I've never tried that below 5.0V, anyone know if there is an issue there?
That probably passed so little current that the poor little mic was starved .a ton of 82k resistors in a series

You cannot make the output of a 7805 go less than 5V. Use an LM317 to make 1.5V.

The electret mic that is powered from an AA battery cell is different from an ordinary 2-wires electret mic that needs a resistor from its output to a positive voltage so that the Jfet can draw about 0.5mA. the battery powered mic probably uses a 3-wires electret mic with its Jfet as a source-follower. Then DO NOT use a resistor to the positive supply, instead it might already have or needs an external resistor to 0V instead. The datasheet of the microphone powered with a battery might not even show you how to power it from a power supply.
Depending on how the power is connected to the mic, it may not be possible to power it the way you intend.
Do you know, for instance, if the negative supply rail is common with the output ground?
I did contract the manufacture and they said I could use a LM317 to power it. I don't think they understood the whole common ground thing. I suspect English isn't their first language. Thank you for all you help on this!Ask the manufacturer of the mic how it can be powered with an LM317 that has its - common to the audio ground.
