for which application ? would you draw a circuit if possible ?
In general , you have to select the value of the resistor so that the current doesnt excced a certain value.

Hi
4.7K - 10K is a typical value.
but in particular application maybe other.

it depends on many things, such as allowed current, voltage head-room, and noise, and some other parameters all depend on application..

Hope that helps,
Ahmad

Can you send your schematic or give an explanation of your circuit please?

Thanks

There is no universal solution/calculation for every circuit. You must give your specific circuit.

the resistor will be ur current limiter , i.e. it depends on the current to be drawn , and keep in mind not to exceed the maximum current provided by ur source
