Hello, I am new to electronics and I have a project to interface an active electrode that need a clean 7.26V (+- 0.02V) supply voltage. I would like to use a 9V battery. The active electrode comsumes 0.7mA. Can I simply use a series of resistors or do I need a voltage regulator or a converter?
Thanks

You could use a precision reference and an op-amp to scale the output voltage. Your current requirement is well within the output current capabilities of an op-amp.
There are numerous adjustable low-dropout voltage regulators which would do the job.

9V is a "nominal" voltage, if it is a rechargeable battery it could be as low as 8.4V. have a look at
