10x LM317T pcb development board PC power regulator 3,4.5,5,6,7.5,9,12 volts

You get 10 Power regulators for a PC you can set the voltage at 3,4.5,5,6,7.5,9 and 12 volts using jumper links and the output polarity can be set by jumper links. The output current is 300ma on 3 volts and about 700ma on 9 volts. The circuit uses the LM317T regulator which has a maximum current just over 1 amp it is a little less in this circuit because the heatsink is quite small. The power input socket is a standard floppy disk plug and the output lead is 1.45M long with 2.1mm DC plugs on each end.
