Hi there,
my embedded system is based on a Cyclone III powered using an external 3.3V power supply. I already found the solution used in DK-DEV-3C120N to drive 1.2V (core) and 2.5V (PLLs) using a 3.3V supply. But I'm still locking for a smart solution (i.e., low price and small area) to supply a smaller device (i.e., EP3C40F484C6N) with a lower power consumption efficiently. Can anyone help me with that? Thanks in advance ModellpilotLink Copied

The best soultion depends mainly on the power demand of your application, particularily for core supply. It may range from a few 10 mA to several A. Linear voltage regulator solution may be suitable up to at least some 100 mA, it's clearly the cheapest solution.

To give a ballpark figure, we are talking about 300..500 mA. Do you have any suggestions regarding the voltage regulator (maybe including a schematic)?
