It is frequent reading someone extolling the capability of a PSU 's output to reach down to 0V. While it could be reasonable to have a minimum output of maybe 1V, or even 0,5V (guessing here), why 0? What for?
Assuming the common in a circuit is 0V, the output now in 0V, how equal is it to that common, on account of all the electronics in the middle, allowing me to reach that value?
Most of the common lab PSUs are not able to sink current and, at 0V why could be it different?
