Hi all,
I want to convert 5V (USB) to 3V to power a microcontroller. I generate the 3V using a voltage divider and want to buffer this voltage. So i need a DC buffer.
I know it is possible to implement this using an opamp. But i was wondering what kind of topologies are there based on transistors (BJT's or FET's).
Thank you in advance.
