A voltage control circuit does not "output a current". How are you measuring this? Are you putting an ammeter between the signal and ground? If so, do not do this, you are likely to destroy something. An ammeter is essentially a short circuit.
The input using the control circuit will draw only as much current as it needs, independent of how current the voltage source can supply. It is typically in the microamp region.
