    Which micro controller? Have you looked in the datasheet? Datasheets usually give the maximum current which can be sourced or sunk by the output pins. Actual current will, of course depend on loads. Can you supply a schematic?

    If you are using PIC microcontrollers they can source/sink 25mA.
