ABSTRACT:
A voltage dropping circuit for a semiconductor device is provided. The voltage dropping circuit includes a control unit for producing a reference voltage from a first specified voltage, an output unit for generating a second specified voltage which is a half of the first specified voltage in accordance with the reference voltage, a timer circuit for generating a driving pulse which becomes active intermittently, and a switch circuit for operating the control unit when the driving pulse is active and stopping the operation of the control unit when the driving pulse is not active.
