In Reply to: 2.5V voltage drop? posted by 1973shovel on November 17, 2014 at 13:36:11:
You're using the 'regulated' term loosely. The DC can be rectified ADD filtered, but when you put it through a regulator, it 'drops' the voltage AND consumes some energy doing so. There are 'low drop-out' regulators, but I hear that they are undesirable because they are noisy or something, so most regulators are full drop out, typically about 2.5V. Only something to worry about if you are inserting into an existing circuit, and if all you do is replace one regulator with a similar, but better, one, the voltages hardly change.Most gear can run within a range of voltages AFAIK. Usually +-10% is expected, but I believe a greater range is often possible, if one is stuck with a particular transformer, for instance.
