    hi
    I am a newbie to electronics and was making a project which required LM 78xx and 79xx ic'c for various voltages like +5.-5,+12,-12.The outpur currnet should be about 500mA max.I was wondering if the current requirment was lower or higher what capacitor values need to be changed and how are these values calculated mathematically .Thank you for your replies in advance :)
