摘要: A semiconductor device including a voltage regulator is disclosed. The voltage regulator may include a multipath amplifier stage, a driver stage coupled to the multipath amplifier stage, a dynamic compensation circuit coupled to the multipath amplifier stage, and a current compensation circuit. The dynamic compensation circuit may be operable to provide a varying level of compensation to the multipath amplifier stage, where the varying level of compensation proportional to a current level associated with the load; and the current compensation circuit may be operable to allow a minimum current level at the driver stage.

摘要: A brown-out detection circuit comprises a first resistive element, a first transistor, a second transistor, and a comparator. The first resistive element has a first terminal coupled to a first power supply voltage terminal, and a second terminal. The first transistor is of a first conductivity type and has a first current electrode coupled to the second terminal of the first resistive element, a control electrode, and a second current electrode. The second transistor is of a second conductivity type and has a first current electrode coupled to the second current electrode of the first transistor, a control electrode, and a second current electrode coupled to a second power supply voltage terminal. The comparator has a first input terminal coupled to the first terminal of the first resistive element, a second input terminal coupled to the second terminal of the first resistive element, and an output terminal for providing a brown-out detection signal.
