摘要:A regulator circuit and a method for regulating an output voltage. Theregulator circuit includes an undervoltage protection stage capable of operating in aplurality of operating modes. In one mode, the undervoltage protection stage
compensates for a low undervoltage appearing in the output voltage and in anothermode it compensates for a large undervoltage appearing in the output voltage. Whenthe output voltage has a low undervoltage, a portion of the current from a currentsource is routed to a feedback network to balance the input voltages of theundervoltage protection stage and to place the voltage regulator in a steady stateoperating mode. When the output voltage has a large undervoltage, the undervoltageprotection stage turns on a current sourcing transistor that cooperates with the currentfrom the current source to quickly charge a compensation capacitor and increase thepower appearing at the output of the voltage regulator.
