    In potentiostat ( Three Electrode System) of electro-chemical, I need to apply negative voltage range from -1.50 to -0.30 DC V (up to 50 mA range) as a source power to electrodes, and that the negative voltage source must be very precise and accurate.

    I am also thinking about PIC or Arduino microcontroller, if I can do on it..

    Please suggest for circuit and/or microcontroller….

    Let's consider AC negative voltage range is the change of polarity So change the terminal of DC voltage that become negative voltage. if you want to do this microcontroller then use L293D to switch polarity .
