![]() 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). ![]()
