Better undestanding the BS2 Vdd 5v amps...

Hello. I have recently started in this world and I really liked it. I'm spanish, so please use simple words with me. Here is my fist question:
I have a SumoBot Rev D. I have 5 IR's emitter and detectors and 1 PING sensor, as well as a piezo speaker. I use 4 1,5v batteries so I provide 6v to Vin and then the BS2 gives me 5v·in Vdd. In the BS2 documentation I can read than each I/O can sink and source about 25 mA. My question is: What is the limit of mA when conecting things to Vdd when they are not conected to any I/O pin? All the IR receptor and the PING need Vdd (+5v) and Vss (ground 0v) justo to keep them working even if you dont need to read the sensor. Is there a limit of mA in this case?
Thanks you very much.
