How many integrated circuits do ... smooths out the ripple. (Hint: more is better.) And then it’s off to build. The end result is a very simple unregulated power supply — just a diode bridge ...

Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit ... as much AC ripple as possible.

PSRR measures how well a circuit rejects ripple coming from input power supply at various frequencies, measuring system performance with a ripple (e.g., sinusoidal ripple) of specific amplitude and ...
