Did anyone play around with the supply voltage to see if it still works at less than the recommended 3.3V? I'd be very interested to know how a lower suppy voltage affects (reduces) current draw.
Background: a PT2399 is specified at about 25 mA current draw at 5V, with a minimum allowed 4.5V. I found that it still works fine at 3V (at least the original PTC, does, as well as one clone), where it draws as low as 8mA!
