摘要

This paper presents the problem of modelling the linear 3-terminal positive-voltage regulator MA7805 (IC) with selfheating taken into account. In the construction of the ElectroThermal Macromodel (ETM) the modified electrical SPICE-library model of the considered device has been used. This macromodel has been implemented to SPICE with the use of the ABM option. The proposed macromodel was verified experimentally and a good agreement between the calculation and measurement results was obtained.
