Replace Q1 with a transistor which can actually handle this current and dissipation. 2N3904 cannot. I suggest D45H11, which will have hFe around 200. Calculate current through R4, with input voltage varying from 30 to 40V. Notice circuit does not work, as Q1 base current is higher than what R4 can provide. Regulated Power Supplies Learn About Electronics In Fig. 2.2.1 R S and D Z form a simple SHUNT regulator as described in power supplies module 2.1. In this circuit however, they are used to provide a stable voltage reference V Z at the base of Tr1. The emitter voltage of Tr1 will be typically about 0.7V less than the base voltage and V OUT will therefore be at a lower voltage than the base. Voltage Regulator Circuits Linear Voltage Regulator ... As you can see the circuit diagram for Series Voltage Regulator, NPN transistor T1 is the series element and a zener diode is used to provide the reference voltage. When the output voltage increases the base emitter voltage decreases, due to this transistor T1 conduct less.
