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 ...

In predominantly digital systems it is often necessary to include linear circuit functions. Traditionally, separate power supplies have been used to run the linear components (see Box, “Linear Power ...

This is a voltage regulator circuit that uses a 7805 voltage regulator to provide a steady 5V output. Here's a breakdown of the components and their roles: J1 (PJ-002AH): This is a DC power jack ...

This project is an electronic power supply circuit that can be powered by either 12V (AC or DC) or 220V AC, and outputs regulated 5V or 3.3V DC. It includes input protection, voltage regulation, and ...
