Extra exam question E7D08
Subelement E7, PRACTICAL CIRCUITS· Group E7D
What type of circuit is shown in Figure E7-2?
- A.Switching voltage regulator
- B.Common emitter amplifier
- C.Linear voltage regulator (correct answer)
- D.Common base amplifier
WhyFigure E7-2 shows a linear voltage regulator circuit. Figure E7-2 shows a linear voltage regulator: a series-pass transistor (Q1) controlled by a Zener reference (D1) continuously adjusts its conduction to hold a steady DC output voltage, the classic series-pass linear regulator topology, with no switching or chopping elements present, answer C. It isn't a switching regulator (no inductor or PWM switching element is present), and it isn't simply a common emitter or common base amplifier, those describe general-purpose amplifier configurations, not this specific voltage-regulating circuit.
