Abstract: An integrated circuit (IC) regulator includes a pass element and a buffer. The pass element has an input terminal coupled to the regulator input, an output terminal coupled to the regulator output, and a control terminal and the buffer has an output coupled to the regulator output. A pass element current between the input terminal and output terminal is independent of the load current associated with a functional circuit of the IC and the buffer is configured to shunt any portion of the pass element current that is greater than the load current.
