Advantages and disadvantages of linear power supply

1) Advantages : Little noise because the output waveform

of transformer is sine wave.

2) Disadvantages :

Additional margin is required because Vs is chan-

ged (depending on power source). (The regulator
loss is caused by margin design).

Greater core size and condensor capacity are ne-

eded, because the transformer works on a single
power frequency.
