There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...

IC references are popular with circuit designers because they are accurate and exhibit low drift. Some of my future columns will cover the three types of IC references: buried zener, bandgap, and XFET ...

We’re quite sure that all hobbyists have used the 7805 voltage regulator at least once in their lives. They are a simple way to regulate 7V+ voltages to the 5V that some of our low power projects need ...

Figure 2 Bootstrapping the IC switch voltage to the input in the circuit of Figure 1 improves efficiency by about 3%. Of course, the FET actively turns on when the source goes low. But simply using ...
