 Bigger Bigger  Smaller Smaller  Reset Reset

In my project I have stabilized 5V power supply to power Arduino Mega 2560.
May I connect it to +5V pin ? Will it not damage Arduino builtin stabilizer, or will not the stabilizer take some (significant) current ?

The term you want is "regulator".

You can put regulated 5V on the pin.
