Term
Intergrated
Definition
Many voltage regulators in today's fast envolving electronics world have become ___________.
Term
Unregulated
Definition
Which type of power supply changes AC to pulsating DC?
Term
Transistor
Definition
It is often an advantage to use _________ in a regulator circuit to a handle current restrictions and linear operation to maintain a more constant output voltage.
Term
Zener Diodes
Definition
A component that will provide control of the output voltage is a ________.
Term
breakdown voltage
Definition
The schematic designator (Vz) stands for __________.
Term
Input, Rectifier, Filter, Regulator, Protection Circuit
Definition
What are the five parts of the power supply?
Term
Regulator
Definition
What circuit maintains a constant output voltage with certain pre-defined limits?
Term
variation
Definition
The regulator circuit is responsible for eliminating DC voltage _______ caused by the input or load.
Term
Allows current to flow in the reverse direction if the breakdown voltage is met.
Definition
How is a Zener Diode is different from other diodes?
Term
It drops the remainder amount of voltage not used but the Zener Diode & Load.
Definition
What does the extra resisitor in a parallel voltage regulator do?
Term
Regulated Power Supplies
Definition
The circuit that maintains the output voltage of a power supply with certain pre-defined limits
Term
precision , stability
Definition
Regulated power supplies provide _________ and __________ needed by some circuits and equipments. 
Term

Series Regulator

Parallel Regulator

Definition
Two different setups of the regulator circuit in a power supply.
Term
Short
Definition
When in foward baised what will a Zener Diode act like?
Term

If knee voltage is meet then will act as short.

 

 

If knee voltage is not meet then it will act as a open.

Definition
In reverse baised what will a Zener Diode act like?
Term
Avalanche breakdown will occur and reverse current flow through the diode.
Definition
What is it called when reverse biasing voltage becomes overwhelming and the depletion zone completely overtakes the two pieces of doped material?
Term
voltage regulation
Definition
The most common use for a Zener Diode?
Term
The increase in load voltage willl decrease the forward base bias and raise the DC collector to emitter resistance of the transistor. This will increase the collector emitter voltage drop and prevent the load voltage from rising.
Definition
If voltage across the load tries to increase what happens with the Zener Diode?
Term
Zener Diodes
Definition
_____ _____ may be connected in series across the DC power supply to obtain two or more voltages.
Term
automatically
Definition
The Zener diode will __________ adjust its internal resistance to compensate for changes in line or load.
Term
Regulated
Definition
