A voltage regulator has the following ratings: Vin = 10 Vdc to 15 Vdc, IL = 20 mA maximum), and regulation = 0.01%. Which of the following statements is true?
A) The load current demand on the regulator cannot exceed 20 mA.
B) The rated output voltage must be some value that is less than 10 Vdc.
C) The rated output voltage falls somewhere between 10 Vdc and 15 Vdc.
D) As long as the input voltage remains within its rated range, Vout will equal 0.01% of Vin.

CA) The statement "The load current demand on the regulator cannot exceed 20 mA" is true because the specification IL = 20 mA maximum indicates the maximum current the voltage regulator can supply to the load.C) The statement "The rated output voltage falls somewhere between 10 Vdc and 15 Vdc" is true because the input voltage range (Vin = 10 Vdc to 15 Vdc) specifies the range within which the regulator can operate effectively, not the output voltage directly. However, the output voltage must be less than the input voltage for the regulator to function, implying it falls within this range under normal operation conditions. The regulation specification does not directly indicate the output voltage level but rather how stable the output voltage is under varying conditions.
