Notes for this at www.learn.org.au UEENEEH138A. Using the LM723 voltage regulator in a very typical circuit giving voltage (and current) control. All the maths shown to calculate output voltages. In part 2, I'll show how the output voltage folds back to protect the current dissipation of the output transistor.
