A voltage regulator and a method for voltage regulation are described. An adjustable driver is coupled to receive an input voltage, a gating voltage, and first control signaling. The adjustable driver includes driver transistors. The adjustable driver is configured to provide a drive current responsive to the gating voltage. The drive current is provided through one or more of the driver transistors at least a portion of which are selectively gated responsive to the first control signaling. A controller is coupled to receive the input voltage and the gating voltage. The controller is configured to provide the first control signaling responsive to the gating voltage. Control circuitry is configured to provide the gating voltage responsive to load current.
