摘要：
A controlled start-up circuit mechanism in a linear voltage regulator can handle a higher supply voltage at start-up and limits the voltage seen at the devices to be lower than the maximum allowed operation voltage. The circuit may regulate voltage for operating a device coupled to a host when the host supply exceeds that necessary for device operation. The controlled start-up mechanism handles a sudden ramp up or spike of supply voltage relative to the device's operational voltage.
