The picture shows the voltage regulator circuit composed of zener diodes. And, the picture (a) shows the circuit with output of 6V/50mA. Now it introduces the determining method of the each components in the circuit. The input voltage U is 10V~16V, and at this time the output voltage Uo=Uz-UBE. The transistor VT1's UBE is fixed which is about 0.65V. So the VS's stable voltage is Uz=6V+0.65V=6.65V. It could use the RD6.8EB1 zener diode.The picture shows the voltage regulator circuit composed of zener diodes.(a)The circuit with output of 6V/50mA. (b)The circuit which using LEDs to replace the zener diodes. (c)The circuit which using the resistance for voltage dividing. (d) The voltage regulator circuit which has the best performance.
