    teensy3.6 3.3V amper

    hello
    i wonder what is the amper limit of the 3.3v pins in teensy 3.6?
    i read in instruction pinout page that the max is 250ma but its mention only for the 3.3V pin near pin 23.
    what about the 3.3V pin near to pin 24? its allso supply 250ma by it self (in a different 250ma regulator) or all 3.3V pin connected to the same 250ma regulator?
    tnx
    rota

    A quick look onto the Teensy 3.6 schematic will tell you that everything comes from the same LP38691 voltage regulator. So, the maximum current which might be drawn in sum from all 3.3V pins is 250mA.
