Need to create voltage regulator, using a sinusodial wave and a 12 V dc source in series and a load resistor 200 ohms. Voltage output must be 5.7 I Can use op amps, resistors, capacitors, and inductors I have been working at this for weeks and I can not find any information on how to create one using op amps. My textbook does not go over this either, so I am really lost. This is where I am so far i can get 11 V on Vout now, with very little sinusoidial action. But I do not know how to get to my desired Vout.
