Voltage Regulators, Zener Diodes Flashcards
1
Q
In a linear electronic voltage regulator:
A
The conduction of a control element is varied in direct proportion to the line voltage or load current.
2
Q
A switching electronic voltage regulator:
A
Switches the control device on or off, with the duty cycle proportional to the line or load conditions.
3
Q
What device is usually used as a stable reference voltage in a linear voltage regulator?
A
Zener diode.
4
Q
In a regulated power supply, what type of component will most likely be used to establish a reference voltage?
A
Zener Diode
5
Q
A three-terminal regulator:
A
Contains a voltage reference, error amplifier, sensing resistors and transistors, and a pass element
6
Q
