A method and apparatuses for power regulation using an extended current limit are disclosed. The power regulator detects an occurrence of an output current of the regulator exceeding a first current limit, triggers an extended current limit timer based on the detected occurrence, regulates the output current according to a second current limit higher than the first current limit based on a duration of the extended current limit timer, and regulates the output current according to the first current limit based on an expiration of the duration of the extended current limit timer.

A voltage regulator circuit using predictively precharged voltage rails is generally disclosed. For example, the voltage regulator circuit may include a main switching regulator configured to provide a target voltage, the main switching regulator having a first voltage node, a precharge switching regulator configured to provide a precharge voltage, the precharge switching regulator having a second voltage node, the precharge voltage based on a difference between the target voltage and a next target voltage to be provided by the main switching regulator, and a precharge switch circuit configured to selectively couple the second voltage node to an output voltage node based upon a transition from the target voltage to the next target voltage.
