I have a nice power source that provides me a steady 5v. I need to down this voltage to 3.3v and I know I can use voltage divider to that but wouldnt it be a good idea? I know a lot of power would be wasted as heat at the resistor, but should I worry with anything else?
I want to power an nrf24l01+ with 3.3v and I dont want to use voltage regulator and not buck converter either. Can I reliably use resistor to bring this 5v down to 3.3v? I will use decoupling capacitor of 10uF and 0.1uF in parallel with my nrf24l01+, do you think I will get a steady 3.3v this way?
