This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

This circuit of power supply, is very simple and easy to built, it can be assembled on a general-purpose PCB, finding its materials is very easy and cost-small. The output voltage is stabilized and is ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...

Every engineer knows that a stable, well-regulated power supply is needed to perform reliable and consistent circuit and subsystem tests. But what about testing a new power-supply, regulator, or ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...
