Abstract :
A macromodel has been developed for the LM117 adjustable positive voltage regulator. This model predicts AC, DC, transient, and power-up responses. Design formulas for finding the component values of the macromodel which are based on pin measurements are presented. The methodology of development is presented along with experimental and simulated results
