Further, both line and load regulation are better than standard fixed regulators. They are exceptionally easy to use and require only two external resistors to set the output voltage. The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. Resistance value of the above is not ideal but I used to value used, to the ideal of R can be larger because the feedback terminal below only requires 1mA current. Stability of this LM317 slightly better than the 78xx class because it was used as the feedback output is not only a reference voltage (78xx kls can also be used as adjustable by lifting the voltage reference terminal wrote in the ground).
