摘要：
A power supply includes a switching voltage regulator, and a linear voltage regulator coupled electrically in series with the switching voltage regulator. The switching voltage regulator includes a first input for receiving a DC input signal, a semiconductor switching stage coupled to the first input and configured to provide a first DC voltage signal from the received DC input signal. The magnitude of the first DC voltage signal is less than the received DC input signal. The linear voltage regulator includes a semiconductor current pass stage coupled to the output of the semiconductor switching stage and configured to provide a constant second DC output voltage signal from the first DC voltage signal. The voltage regulators are implemented together within a common integrated circuit housing.
