Is it possible to use diode to convert 5V to 4.4V for power supply?

It is not recommended to use this method, because the forward voltage of diode will change as the current changes, which will cause the instability of the module’s power supply and make the module work abnormally.It is not recommended to use this method, because the forward voltage of diode will change as the current changes, which will cause the instability of the module’s power supply and make the module work abnormally.

LM2576-ADJ is the regulator I used, It works fine
