rheot-what? oh boy
Circuit Version 2.0:
Hopefully the calculations are ok
Im just not too sure about the resistors capability to handle the Watts that go throu them (because im not sure how to calculate them).
Using W = V^2 / R
W = 7.2V^2 / 0.88ohm
W = 51.84V / 0.88ohm
W = 58.9W
if this is correct, regular resistors are going to catch fire really fast =D
Not even the 5W resistors i bought would handle that.
Hopefully its just me , not doing the calculations the right way.
According to this calculator: http://diyaudioprojects.com/Technical/Voltage-Regulator/
my Voltage Regulator is only handling 1.774Watts wich seems ok. (image edited)
however, according to this video:
Power = (vIn - vOut) * iOut;
Power = (12v - (3.6v+3.6v)) * 1.4a
Power = 6.72W
wich is ok i guess, with a decent heatsink.
Maybe the 1.774Watts is the power that the R1 / R2 are going to have to handle. and that seems alot better than 60Watts
Also added a 0.1uF capacitor as suggested by the datasheet
