ABSTRACT:
A voltage regulator for a microprocessor unit provided with a reset circuit for the microprocessor unit. Voltage from the regulator circuit is applied to the reset circuit as well as to the microprocessor unit. The production of a reset signal during a rise time of the regulator circuit is prevented by delaying generation of a reset signal until the regulator voltage to be applied to the microprocessor level has reached an operating level. The regulator circuit and the reset circuit are commonly formed in an integrated circuit so as to eliminate the wiring therebetween and to reduce size. Further, the reset signal is produced by the reset circuit when a run signal indicative of the proper execution of program steps is not produced at a regular rate.
