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 ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices. Their ...

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 ...

Characterized by tight regulation, low noise, and high stability, Calex Mfg. Co.’s Model 3.15.5-115 low-noise linear power supply is suited for use as a dual 15-V rail source with an added 5 V dc ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...
