After rereading your question, I think I may have misinterpreted your question. Did you mean you want the output to be between 0 and 5 volts or from 0 to 5 volts. If you want it from 0 increasing to 5 volts you will need additional electronics on the output, there are more qualified people on this forum to answer this then myself, but I would use a switching transistor on the output.
