Abstract
A current limiting circuit capable of increasing a range of applicable load values is disclosed. An output circuit () may include a current limiting circuit. A current limiting circuit may include a voltage detecting circuit () and a voltage clamping circuit (). A voltage detecting circuit () may detect a plurality of output voltages (Vout). Voltage clamping circuit () may clamp a control terminal of an output transistor (M) to a plurality of clamped voltages in response to the plurality of detected output voltages (Vout). In this way, an output transistor (M) may have a plurality of current limitation values as an output voltage (Vout) changes. By doing so, an output circuit () may be applicable to a multitude of load (LOAD) values and properly operate without risks of overcurrent or undesired quiescent operating states being entered, as just two examples.
