Disadvantages of the linear regulator:

Linear regulator waste power in the form of heat.
Linear regulator has very low efficiency.
Linear regulator cannot be used for the step-up purpose.
Linear regulator is not suitable for large power applications.
Linear regulator has only one output.

Advantages of switching regulator over linear regulator:

Switching regulator have more efficiency than the linear regulator. Switching regulator have about 70 to 90 percent efficiency.
Switching regulator is used for both step-up and step-down operations.
The cost and size of the switching regulator are advantageous as compared to the linear regulator for larger applications.
By adding windings switching regulator can provide more than one output voltage.

Continuous mode and discontinuous mode switching regulator:

In the continuous mode switching regulator, the switch is turned on before the stored energy in secondary winding gets empty.
In Discontinuous mode switching regulator switch is turn on after the stored energy in secondary winding gets empty.
This is the difference between continuous mode and discontinuous mode switching regulator.
