might this may help you by doing this in mplab

i have made one but not satisfied with result because i want more dot matrix. i am confused that by using more dot matrix my scan or say refresh rate will decrease does any body here have experience of working with more dot matrix if yes than please provide some solution.
78xx are good cheaper and easy to use but if you want a good switching regulator with line voltage regulation than you must go for lm2575 it will not be cheaper
your vs is 15 max so i = 15/200 = .075 A and the power consumption will be i2r that will be .075*.075*200 nearly 1.125 that means you will require 2 watts zener diode and 2 watts resistor for your design
