In our setup now, these are the values we're going to use. We're going to put 12 volts into the voltage regulator and regulate it down to 5V. Based on the formula above, in order for the LM317 to output 5 volts, the value of R2 must be 720Ω. Set this above circuit up and...
If we replace the low-side resistor of the divider from the LM317 voltage regulator circuit diagram with the load, then the resulting configuration of the LM317 regulator will regulate the current to a load. Hence, this LM317 circuit can be treated as LM317 Current Regulator Circuit. LM317 ...
