Managing linear regulator transient voltages upon sleep transitions

A method of operating three or more ballast devices of a linear voltage regulator, comprising:

• producing a voltage at an output terminal that is electrically coupled to a first one of the three or more ballast devices;
• receiving a power mode indication;
• activating a first additional ballast device of the linear voltage regulator to add first additional capacitance to a load corresponding to the power mode;
• generating one or more ballast control signals, in succession, in response to a change in the power mode indication, wherein each successive ballast control signal is delayed relative to when the change in the power mode indication occurs;
• and
• activating, using the one or more ballast control signals, second additional ballast devices of the linear voltage regulator to add second capacitances to the load of the linear voltage regulator.

A linear voltage regulator that varies a load on an output based on a change of power mode indication signals, the linear voltage regulator comprising:

• LDO circuitry to receive, in succession, a plurality of ballast control signals in response to the change of power mode indication signals, wherein each successive ballast control signal is delayed relative to when the change of power mode indication signals occurs;
• a pass element comprising at least one first ballast device and a plurality of additional ballast devices that are individually controlled by respective instances of the plurality of ballast control signals;
• and
• an error amplifier comprising at least one ballast control circuit that is coupled to at least one of the ballast control signals.
