Regulator with device performance dynamic mode selection

IN IN OUTOUT A voltage regulator device and accompanying methods are provided for providing efficient voltage regulation to an electronic device. Efficient regulator receives an input voltage on Vfrom a battery or some other power supply at node Vand supplies a stable regulated voltage to load device at node V. Load device pulls different amounts of current and requires different degrees of tolerance on the voltage at Vdepending upon its operating conditions. Data collection and control circuit is capable of enabling and disabling regulator and regulator . Data collection and control circuit is also capable of measuring certain performance parameters associated with load device and the operating conditions of load device . Data collection and control circuit enables regulator if said operating conditions are such that when data collection and control circuit enables regulator the performance parameters associated with load are below a predefined standard.
