■ Maximum input voltage 30V

■ Output voltage range 3.0V~5.0V

　MD71H30, output voltage 3.0V (7130H);

　MD71H33, output voltage 3.3V (7133H);

　MD71H36, output voltage 3.6V (7136H);

　MD71H44, output voltage 4.4V (7144H);

　MD71H50, output voltage 5.0V (7150H).

■ Output current 30mA

■ Quiescent current 1.2uA

■ Accuracy ±3%

■ Package type: TO-92, SOT-89, SOT-23

Application

■ Use a regulated power supply for battery powered devices

■ Regulated power supply for communication equipment

■ Stabilized power supply for home appliances and toys
