Which figure states how far the output moves as the current drawn changes?

  • A.Output change per unit change of load current
  • B.Output change per unit change of input voltage
  • C.The maximum current the regulator can deliver
  • D.The efficiency of the regulator at full load

Answer: A

Load regulation is how far the output moves as the load current changes, and in a shunt regulator it follows almost entirely from the diode's dynamic resistance. Line regulation is the response to input change, maximum current is a rating, and efficiency is a separate figure. Two regulation specifications, one for each thing that can vary, is the pattern every power supply data sheet follows.
