Topic: Analog Circuits

In a feedback series regulator circuit, the output voltage is regulated by controlling the

  • A. Magnitude of the I/P voltage
  • B. Gain of the feedback transistor
  • C. Voltage drop across the series pass transistor
  • D. Reference voltage

Answer: D. Reference voltage

Explanation: In regulator circuit, output does not change due to the change in the load voltage or the input. But the output can change due to change of reference voltage.
