I have search high and low but so far I have been unable to find a reference to the maximum amount of current that can be drawn out of the 3.3v & 3.3v* pins. The Vreg is specified at 500mA and the core uses <300mA so the remainder, 200mA, should be available at the pins. That is assuming that the design and layout has been done with these specifications in mind. Is it a valid assumption that I can draw 200mA ‘forever’ and not damage the device? I would hate to smoke the regulator because of a bad assumption.
