    Feb 10, 2014 · One of the best ways of understanding operation of a transistor or a circuit is to examine how an output of interest responds to an excitation change. For the NPN transistor in question, we want to examine how the output current, in this case, the collector current, changes when the collector-emitter voltage VCE, which is set by V1, sweeps say ...

    Keep the PNP’s emitters on the output side of the circuit. Equations: Rz = (Vin − Vzener) / (Iz + K * Ib). Ib = Iload / Beta_min. Iz is the needed zener current. Ib is the needed Q1 base current. K is 1.2 to 2 for headroom. Beta_min is the smallest usable DC current gain of the transistor. Example Shown: 12v, 1 amp out, table:
