The Arduino Uno already has a 3.3V pin, but it can only provide upto 50 mA. For my purposes (esp8266), I needed to supply a constant 3.3V with current that could go as high as 170 mA. The Uno's 5V pin ...

The idea was to make a 5V 50Ω buffer, but this easily converted into a 3.3V 50Ω output despite the 5V rail by switching in three resistors (see diagram). Update: for a 10:1 attenuator for a 50Ω output ...
