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. Recently, there has been ...
The aim: Create a 3.3V source from a –5V supply. You can obtain a precise, positive-output voltage from a negative-voltage supply with a boost converter and a linear regulator. The input and output ...
