Provided is a digitally-controlled linear regulator having noise-shaped component selection. The digitally-controlled linear regulator has a regulated-voltage sensor, a comparator module, a quantization module, and an impedance switching network. The regulated-voltage sensor is operably coupled to sense an output voltage of the digitally-controlled linear regulator to produce a sensed output voltage. The comparator module is operably coupled to compare the sensed output voltage with a reference voltage at a predetermined clock rate to produce a digital regulation signal. The quantization module is operably coupled to quantize the digital regulation signal to produce a quantized regulation signal. The impedance switching network is operably coupled to convert a source voltage into the output voltage of the digitally-controlled linear regulator based on the quantized regulation signal.
