How does a linear electronic voltage regulator work?
It has a ramp voltage as its output
It eliminates the need for a pass transistor
The control element duty cycle is proportional to the line or load conditions
The conduction of a control element is varied to maintain a constant output voltage✓الإجابة الصحيحة
الشرح
A linear regulator compares its output against a reference and continuously adjusts how hard the control element conducts, dropping whatever voltage is left over so the output stays constant. Nothing is switched, and the surplus power becomes heat in the control element.
