J'ai regarde' la...On dirait un Volt-mod....<br />J'ai regarde' la doc du composant: <br />"PIN FUNCTIONSU U U (5-Lead/7-Lead)<br />SENSE (Pin 1): This pin is the positive side of the reference<br />voltage for the device. With this pin it is possible to Kelvin<br />sense the output voltage at the load.<br />ADJ (Pin 2/5): This pin is the negative side of the<br />reference voltage for the device. Transient response can<br />be improved by adding a small bypass capacitor from the<br />ADJ pin to ground. For fixed voltage devices the ADJ pin<br />is also brought out to allow the user to add a bypass<br />capacitor.<br />GND (Pin 2, 7-Lead Only): For fixed voltage devices this<br />is the bottom of the resistor divider that sets the output<br />voltage.<br />VPOWER (Pin 5/6): This is the collector to the power device<br />of the LT1580. The output load current is supplied through<br />this pin. For the device to regulate, the voltage at this pin<br />must be between 0.1V and 0.8V greater than the output<br />voltage (see Dropout specifications).<br />VCONTROL (Pin 4/3): This pin is the supply pin for the<br />control circuitry of the device. The current flow into this<br />pin will be about 1% of the output current. For the device<br />to regulate, the voltage at this pin must be between 1.0V<br />and 1.3V greater than the output voltage (see Dropout<br />specifications).<br />VOUT (Pin 3/4): This is the power output of the device."<br /><br />Marcohttps://www.blogger.com/profile/16054005873327759616noreply@blogger.com
