My first variable power supply using LM317 - ElecCircuit
Variable power supply using LM317, 1 to 30V at 1A. This is the first DC power supply in my life that made to use in many projects. It is ideal for those who want to adjust voltage from 1 to 30V and currents up to 1A.
Variable Voltage Power Supply Using The LM317T
ExampleSpecificationsApplicationsOperationFunctionAdvantagesPerformanceIntroductionMechanismContinuing on from our tutorial about converting an ATX PSU to a bench power supply, one very good addition to this is the LM317T positive voltage regulator. So suppose we want an output voltage of +9 volts from our PSU bench power supply, then all we have to do is connect a +9v voltage regulator to the +12V yellow wire. As the PSU has already done the rectification and smoothing to the +12v output, the only additional componentSee more on electronics-tutorials
Variable Power Supply using LM317 Voltage Regulator
The most important part of this circuit is the 317 variable voltage regulator. The 317 is a monolithic integrated circuit with adjustable 3-terminal positive-voltage regulator designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 V to 37 V range.
0-28V, 6-8A Power Supply Circuit using LM317 and 2N3055
0-28V, 6-8A Power Supply Circuit Diagram using LM317 and 2N3055 This design can produce a current of 20 amps with little modification (use proper rating transformer and a huge heat sink with fan). Huge heat sink is required in this circuit, as 2N3055 transistors produce large amount of heat at full load.
