The problem is that my supply voltage is pretty much capped at 4.8 volts, and I am using a single supply op amp, so Vcc = 4.8V (insead of +-4.8V).
That is why I was leaning toward using a PNP instead of an NPN. I switched my input to go into the negative and I now have positive feedback. The...
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...
