    Abstract: A regulator circuit has a first non-operating state, a second non-operating state, and an operating state. The regulator circuit includes: a detection circuit that detects a magnitude of an output voltage of the regulator circuit, and outputs a feedback voltage that indicates a result of the detection to a feedback node; an operational amplifier circuit that compares the voltage of the feedback node with a reference voltage, and outputs a voltage that indicates a result of the comparison; and an output circuit that generates the output voltage according to the voltage output from the operational amplifier circuit. A state of the feedback node is different between the first non-operating state and the second non-operating state, and a transition time required to switch from the second non-operating state to the operating state is shorter than a transition time required to switch from the first non-operating state to the operating state.

    Abstract: A regulator circuit includes: a voltage detection circuit that detects a magnitude of an output voltage of an output node, and outputs a feedback voltage that indicates a result of the detection; an error amplifier circuit that compares the feedback voltage with a reference voltage, and outputs a voltage that indicates a result of the comparison; an output circuit that supplies an output current to the output node according to the voltage output by the error amplifier circuit; a current detection circuit that detects a magnitude of the output current; and a current bias circuit that supplies an output bias current to the output node, and increases or decreases the output bias current based on a result of the detection of the current detection circuit.

    Abstract: A screen printing machine includes a printing execution unit which fills a pattern hole of a mask with solder by sliding a squeegee on the mask contacting a board and thereafter separates the board from the mask. The screen printing machine further includes: a library which stores printing conditions, each of which includes operation parameters of the printing execution unit and corresponds to a combination of options of selection items which include aboard type, a solder type, and a squeegee type; an option display unit which displays the options of each selection item in an image display area; and a printing condition setting unit which reads out, from the library, a printing condition corresponding to a combination of selected options, and which sets the read-out printing condition to a printing control unit which operates the printing execution unit.
