I got a bunch of LM 317T's wich is rated at 1.5 amps, and i need about 5
amps for an fan control circuit.
(I know an PWM circuit would be more efficent but i need to read the strobe
pulse)
It is possible to parallel LM317s, but you can't simply connect their pins
together. A few more componenets are needed. Have a look at:
http://www.national.com/ds/LM/LM117.pdf
There is a typical app that shows how to do it. You could also use a pass
element to increase the output current. Check the typical apps in the above
data sheet.
