This Adjustable +Voltage Power Supply Project Kit is designed around the LM317T 3-Terminal Adjustable Voltage Regulator in the TO-220 package. It is capable of supplying in excess of 1.0 Amps over a range of 3 volts to 25 volts output. This kit consists of the PCB, Schematics, and parts required to build a 1-amp (or more), highly regulated Adjustable DC Power Supply. It requires an input AC or DC voltage source (3 V to 30V) from a transformer, such as a wall-mount type. A heat sink (not supplied) may be needed for the LM317T, depending on your application. You will need soldering tools and basic soldering skills. The output voltage is varied with a potentiometer and is very steady and accurate even while the input voltage varies. The output can be varied from around 1.2VDC up to 25 VDC depending on the input voltage and the choice of resistors. This circuit is perfect for those that want their own small but powerful power supply. It can be used on the bench or as part of your project.
