In my current design I need a very clean +5V supply for my ADC circuit.
I have measured the current value of the input supply range to be approx.: 4.3V - 5.2V however in the final design the range might be slightly greater than this !
I will need no more than 100mA on the output.
I need the smallest possible solution however I can't really use a device that has a pitch less than 0.5mm. Also need a standard footprint outline (not something like a X2SON)
I think I will need a Buck - boost to raise/reduce the output to a little above +5V and then use a LDO with the highest possible PSRR.
What do you suggest ?
