Description

LM317 Power Supply Kit 80-680

This kit offers the builder a very basic power supply that can be adjusted over a range of about 1.5 to 35 volts DC.

If you add the heat sink (included), you can run it as “hot” as 2 amps output; otherwise about 60mA at 12 volts.

This is a text book circuit using an LM317, which is a 3 terminal regulator in a TO-220 package.

Input can be either AC or DC; DC input must be at least 2.5V above the required voltage output.

You could use a surplus transformer from 12 volts up for input.

Board size is about 1 1/2″ x 2″ inches.

Kit contains instruction sheet, schematic, screened PC board and 17 components.
