ABSTRACT:
A voltage regulator circuit comprises an error amplifier for generating an error signal responsive to a reference voltage in a feedback signal. A feedback circuit provides the feedback voltage signal to the error amplifier and a driver circuit provides regulated output voltage responsive to the input voltage in the error signal. Short circuit protection circuitry selectively protects transistors within the error amplifier, the feedback amplifier and the driver circuit responsive to a short circuit protection enablement signal.
