METHOD FOR REGULATING A VOLTAGE AND CIRCUIT THEREFOR |
摘要 |
<p>A regulator circuit and a method for regulating an output voltage. The regulator circuit includes an undervoltage protection stage capable of operating in a plurality of operating modes. In one mode, the undervoltage protection stage compensates for a low undervoltage appearing in the output voltage and in another mode it compensates for a large undervoltage appearing in the output voltage. When the output voltage has a low undervoltage, a portion of the current from a current source is routed to a feedback network to balance the input voltages of the undervoltage protection stage and to place the voltage regulator in a steady state operating mode. When the output voltage has a large undervoltage, the undervoltage protection stage turns on a current sourcing transistor that cooperates with the current from the current source to quickly charge a compensation capacitor and increase the power appearing at the output of the voltage regulator.</p> |
