Abstract :
A macromodel for a CA3085 regulator is presented. The CA3085 is an 8-pin, adjustable, positive voltage regulator. Design formulas are presented. The room temperature model is presented first. Then this model is adapted to produce a model to predict results at -55°C and 125°C. Finally, a comparison with laboratory results is presented
