Circuit to power microcontroller from telco current loop

[Guest_imported]

Hi !

I will appreciate sugestions or directions on how to build a circuit to power a microcontroller added into a plain telephone, powering it with 3.3V derived from the off-hook pots telco current loop.

Thanks

i would like to ask, do you have a schematic diagram or circuit that can do a process of multi-tasking for a specific, using tne internet and still you can use your phone line?

thanks

Hello Mikel73.
I am sorry I do not have the circuit you described.

Hi Externet

I take it we're talking milliamps here... So tell us what is the maximum current your controller will draw? I don't have a circuit as such, but assuming the current consumption is fairly constant, then a suitable resistor, zener diode and capacitor ought to do the trick. Hope your telco approves!
