Useful for electronics hobbyists, this linear workbench desktop power supply circuit converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable ...

Figure 1 shows the schematic diagram of the device. The design consists of two main parts: the main regulator circuit and the current-limiting circuit. IC3 is the LM338 5A positive linear regulator. 1 ...

Modern integrated circuits are increasingly vulnerable to power supply noise and the ensuing induced jitter, phenomena that can significantly impair circuit reliability and performance. The interplay ...

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, ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.
