Hello!
I'm designing a SMD circuit. Since it's my first time doing a SMD i was wondering which was the best way to reduce the voltage.
The IC i'm going to use, needs max 3.3V to work. I was gonna use a CR2032 coin cell but is too big for the design. So i was thinking about using a 3.8V Li-Po rechargeable battery and reduce the voltage to no less than 2.7V to power the IC. I know there are some ways to do this, like a voltage divider, diodes or a linear voltage regulator. I must know when the battery needs to be charged so i can´t use a regulator. But i don´t know which one would be the best option for low power consumption and smallest size possible.
Thank you,
GerCer
