Many people wonder how much current the Micro MinimOSD draws so I am sharing it here.
People have mixed reports on how much current the unit draws: 100mA, 250mA, 500mA. Looks like it depends where you buy from, it appears the manufacture is inconsistent across the board... e.g. hardware variations of cheaper ones are creating different power consumption. There are so many manufacturers pumping these things out now.
Don't solely rely on the spec provided on the product page, it's most likely to be a "copy and paste" from another seller/manufacture. My advice is to do your own testing/measurement just in case. Worst case senario is to assume it draws 0.5A (although IMO this will cause overheat on most of the PDB out there nowadays with linear BEC), and make sure your voltage regulator can handle that.
By the way Some need to add capacitor to the power line, just to keep the OSD turned on during punch-outs. That's because the MAX chip is extremely vulnerable to voltage variations and "dirty" power, the cap smooths that out.
