Voltage regulator designed with change to the feedback method as due to EveryCircuit was unable to find a solution to the direct feedback pass the BJT emitter voltage divider feedback.
This voltage regulator circuit uses the same principle of the regular designed of having a Zener diode as voltage "clamping" reference.
Resultant of the Opamp section forms a voltage buffer which have regulated output that has its current amplify by a BJT.
Do note that the buffer output have to be 0.7V higher than the 5V regulated output as there will be Base Emitter voltage drop for silicon base BJT.
