I'm currently researching LDO adjustable regulators to make an adjustable supply that runs from 5V. I want my supply to be capable of supplying down to 0V.
I've found the LT3083, which can adjust down to 0V, however has a 310mV drop out voltage. I would prefer to have a smaller drop out voltage than this. Does anyone know of a similar regulator that meets my 0V requirement, but has a smaller drop out voltage? I am seeking a smaller drop out voltage so that my supply's upper range will be closer to 5V.
