Voltage regulator

A voltage regulator circuit that regulates voltage on an output node that provides power to a load circuit having varying current draw. A feedback voltage from the output node is compared to reference voltages. In response to the comparisons, pull-up/down circuits are applied to a gate-control node...

Zusammenfassung:A voltage regulator circuit that regulates voltage on an output node that provides power to a load circuit having varying current draw. A feedback voltage from the output node is compared to reference voltages. In response to the comparisons, pull-up/down circuits are applied to a gate-control node connected to the gate of a pass transistor. The voltage of the gate-control node is adjusted by integrating current from the pull-up/down circuits. In response to the feedback voltage being between the first and second reference voltages, the voltage on the gate-control node is maintained by disabling the pull-up/down circuits at the gate-control node.
