Abstract
A voltage regulator regulates voltage at a node and has circuitry coupled to the node for providing a current to the node. A regulating transistor coupled between the node and a first power supply voltage terminal has a disabling transistor coupled in parallel and is selectively disabled by directly connecting the first power supply voltage terminal to the node. An inverting stage has an output connected to the regulating transistor. A load transistor has a first current electrode coupled to a second power supply voltage terminal, and a control electrode and second current electrode connected together and coupled to an input of the inverting stage. A sensing transistor has a first current electrode coupled to the second current electrode of the load transistor, a control electrode connected directly to the node and a second current electrode coupled to the first power supply voltage terminal.
