To start with some hard experimental facts, I took a power amplifier – similar to Figure 9.7 – powered by an unregulated supply on the same PCB (the ... variations being reflected in the HT rails. A ...

A higher-power ripple-eater augments the simple design with an additional transistor ... most audio amplifiers can readily operate with an unregulated supply because they do not need to provide ...

(Credit: David Lovett) Much of the confusion came down to not really understanding how this PDP-11/03 PSU design ... the unregulated supply, which is used effectively as a switching mode power ...

(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 with some capacitors on the output — but by using really ...

(Source: Lucasfilm) As described, a linear design is simple, reliable, and if an unregulated power supply meets your requirements, efficient, too. Add regulation, though, and the efficiency plummets.

The main power rail on cards for telecoms and networking should be 8V unregulated, claimed International Rectifier ... This simplifies the design of the card edge converter, producing cost and PCB ...

The prototype of Figure 4 has been tested for linearity by connecting the unregulated DC input to a 22V power supply, V control to a sawtooth generator spanning 0-10V @ 5Hz, and sampling the output ...
