I'm trying to create a simple power supply for a project, but it's not working correctly. I have a reference voltage (4.1V) and a supply voltage (4.8-5.0V). My goal is to connect an opamp functioning as a voltage follower with a transistor used to supply the adequate current. That is a drawing of my circuit, sorry for the quality. Edit: Forgot to mention that it isn't working. My output is stuck at Vcc, when it should be pulled to the same value as my input. Any suggestions would be helpful. Thanks.
