Why 3V3 instead of 3V?
- Why 3.3V instead of 3V?
- Usual values used in doing electronics/power supplies are almost always round numbers:
- - 5V
- - 12V
- - 28V
- - 48V
- - 60V
- I understand that in some cases ICs are built to accept the voltage directly coming from the lithium-ion cell in order to simplify the power stage, therefore, having 4.2V input.
But, what is the reason behind having a 3V3 voltage level omnipresent instead of 3V?
