voltage regulator LM 723 ?

Input 24 vac, throw full rectifier with 1000 UF capacitor. Achieved 7 to 30 vdc output. Used less than a 2 watt load for the test.
I have never built a circuit board before. I am focusing on the regulator. I found this schematic and built it. It works, and then I studied it. It seems that the voltage regulator watches terminal #4 voltages input, mine is 7 Volts. If the voltage drops at terminal #4, the regulator increases voltage out terminal #10 until 7 volts is found again at terminal #4. Is this correct?

Thank you
