Transistor Series Regulator Since Q 1 is an npn transistor, V o is found as: the response of the pass-transistor to a change in load resistance as follows: If load resistance increases, load voltage also increases. Since the Zener voltage is constant, the increase in V o causes V BE to decrease. The decrease in V BE reduces conduction through the pass- transistor,
