ABSTRACT:
An improved regulator apparatus comprises a regulation unit, in response to an operation signal, for regulating an input voltage to provide a regulated voltage to its dependent load and an overcurrent protection unit for blocking the operation of the regulation unit when a short-circuiting occurs in the load. The overcurrent protection unit includes a bypass transistor for bypassing the operation signal to the regulation unit and a diode for sensing the change in the potential level of the regulated voltage to activate the bypass transistor.
