レギユレータ。[Claims for Utility Model Registration] A converter comprising: a first rectifier circuit connected to an AC power supply; a regulator circuit to which a smoothing input is applied from the first rectifier circuit; and a primary winding connected to the regulator circuit. a transformer, a second rectifier circuit connected to the secondary winding of the converter transformer, a switching circuit interposed between the second rectifier circuit and a set load, and a remote control detection unit; and a control circuit that is supplied with power from the second rectifier circuit and drives the switching circuit to open and close based on the detection signal from the detection section, and when the remote control is on standby, the switching circuit opens and opens automatically. The switching regulator is configured to perform excitation oscillation, while when the remote control is turned on, the switching circuit path is closed to separately excite oscillation, and when the remote control is on standby, one of the converter transformers is connected to the regulator circuit. A positive feedback loop is formed that includes a switching element connected to the next winding and a drive circuit connected to the drive winding of the converter transformer, while the drive circuit detects an increase in the power supply voltage and 1. A switching regulator comprising current limiting means for limiting the drive current applied from the switching element to the switching element.
