Abstract
The disclosure is directed to techniques for a pass element in a linear regulator circuit. The pass element is configured with a transistor with a low input capacitance that provides current to the load for light current demand levels. When the output current exceeds a predetermined threshold, the pass element is configured to turn on a second transistor to provide the additional current. The configuration of the pass element with the regulator circuit causes the regulator circuit to operate with a low quiescent current and with large bandwidth for fast response to load changes.
