This is the LM317LZ Variable Voltage Regulator Design Kit with PCB. This kit includes the active components you will need to build several nice, voltage-regulated power supplies. Design several different output voltages to power your projects. It includes the very popular LM317LZ which is an adjustable, 3-Terminal, Voltage Regulator in a TO-92 package capable of supplying in excess of 100mA over an output voltage range of 1.2V to 37V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. It employs internal current limiting, thermal shutdown, and safe-area compensation, making them essentially blow-out proof. The LM317LZ serves a wide variety of applications including local, on card regulation.

This device can also be used to make a programmable output regulator or as a precision current regulator. With high-current pass transistors, you can regulate a much higher current. The Application Notes are on the web at www.vakits.com. Included are enough 1/4 watt Carbon-Film Resistors, Aluminum & Ceramic Capacitors, Signal & Power & Zener & Schottky Diodes, NPN & PNP Transistors, Bridge Rectifiers, Trimpots, LEDs, and some Electronic Hardware for your I/O Interface. To help you develop your circuits, you also get a Printed Circuit Board (PCB) with 162 plated-thru holes spaced at .100". The PCB is 1.1" x 2.0" and is .062" thick.

There are enough different parts to enable you to design a wide range of output voltages. Search the web for incredible circuits to build. We supply the parts, you supply the ingenuity.
