Using a 5.1V-5.5V Power supply instead of a 5V

Post by bladeRF_user1234 »

Hi,

I wanted to know if using a 5.1V-5.5V power supply would damage the bladeRF or cause it to malfunction. From what I've seen, most regulators are rated for 5.5V max or well over 5.5V on the schematic so it should be fine but I wanted to confirm whether it was possible. I'd like to keep the circuit as simple as possible and not have to use another 5V regulator, as I plan to have a 12V to 5.2V buck or something like that, and then have an LDO for other circuits. BladeRF power supply would never exceed 5.5V at most, and it will likely be around 5.2/5.3V.

Would it be okay?

The input voltage to the bladeRF must never exceed 5V. Ensure this is the case even at low current draw from a power supply.
