Hello,
I'm using a LM317 to output 5.10VDC out of 9VDC of the power supply.
The resistors would be 470R (R1) and 1k4 (R2),
I'm not sure regarding how the resistor power should be calculated (1/4W, 1/2W, 1W)? there are no informations on the datasheet and maybe you can help me to find a formula and understand why.
Thanks a lot,
J
