Abstract
A semiconductor apparatus including built-in power supply circuits capable of supplying a large current with high voltage accuracy. The semiconductor apparatus includes a semiconductor chip including a circuit area and power supply circuits, coils and capacitors. The semiconductor chip, coils and capacitors are provided in a package. Each power supply circuit, a coil and a capacitor compose a switching regulator. The semiconductor chip and the package are connected such that a power supply voltage which will be produced by the switching regulator is supplied to the circuit area. The power supply circuit is supplied with a power supply voltage from the outside of the semiconductor apparatus.
