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 ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

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 ...

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 ...

Linear Technology has produced a high-power dual voltage reference, allowing the reference replace the circuit power supply regulator. Specs are excellent, with outputs offering 0.05% initial accuracy ...

DC power supplies for portable devices are expected to be extremely efficient for the reason of energy consumption, longer run time from the battery pack and greener environments. Using ...

The first instrument which comes to the mind of most engineers when it comes to testing a new board is an oscilloscope. While that will help to assess many aspects of the board’s performance, it’s not ...

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...
