This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

Almost in any circuit design, building at least one regulation stage is necessary. Two power supply design options are available, which are linear and switching. The linear regulators are easy to ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...
