Hi, amateur_24. I think you might have your vocabulary mixed up. Do you mean two components that SINK 200mA each? If they source it, it means they deliver it.
If you plan on running both at once in parallel with your power supply, your supply will have to SOURCE at least 400mA.
Sorry I meant they each require 200ma to function so that's SINK right?
This transformer will need to be rectified to DC current because of my LCD and AVR microcontroller. Is the maximum rms value of the rectifier the maximum ac voltage you can supply it?

For a rectifier load you will need a transformer rated at a higher current then the load since the short, high current pulses drawn from the transformer by the rectifier circuit cause higher I²R heating then a resistive load. I would recommend a transformer rated for at least 150% of the maximum DC load or 600mA for a 400mA dc load.
