i am designing a circuit where my o/p is around 5V..now i need to convert this volt o/p to current o/p...can any body pls help me in this...

 

What correlation does your current output need to be with the voltage output, and for what load resistance?

If your load resistance is high, it may be difficult/impossible to get a supply voltage high enough for the desired current. I=E/R.

You should post a schematic image (.png preferred) of your circuit as it exists now. This will help us to help you more quickly, as it eliminates a lot of questions.
