The series of 79 × × of the series of × of 78 × that the integrated circuit of 3 upright stabilized voltage that electronic product middling sees has positive electricity to press output and negative voltage output. Friend name is thought of justice, 3 end IC is to show the integrated circuit that this kind of stabilized voltage uses has 3 output that cite a base only, it is input end, ground connection end and output end respectively. Its appearance seems common dynatron, the standard of TO- 220 is enclosed, the TO-92 that also has 9013 look is enclosed. The periphery component that with 78/79 series IC of 3 upright stabilized voltages comprises place of regulated power supply to need is few, circuit interior still has had stream, overheat and the protective circuit that adjust a canal, use rise reliable, convenient, and low-cost. This series is compositive in model of stabilized voltage IC 78 or the 79 numbers from the back represent this 3 end the output voltage of circuit of compositive stabilized voltage, be like 7806 express to output voltage to be 6V, 7909 express to output voltage to be negative 9V. IC of 3 upright stabilized voltage has 78/79 series production of manufacturer of a lot of electrons, 80 time had, normally prefix is the code name that produces manufacturer, if TA7805 is the product of Toshiba, AN7909 is the product below the pine. (click here, examine about the knowledge that sees prefix identifying integrated circuit) be in sometimes number 78 or 79 from the back still have a M or L, be like 78M12 or 79L24, use distinction to output electric current and enclose a form to wait, among them the electric current of the biggest output of 78L attune series is 100mA, electric current of the biggest output is 78M series 1A, electric current of the biggest output is 78 series 1. 5A. Its enclose also have a variety of, detailed sees a picture. Plastic enclosed stabilized voltage circuit has setup easy, price is low wait for an advantage, because this is used morer. 79 series are besides output voltage negative. Derivative foot is arranged different beyond, name method, appearance to wait all with 78 series identical. Because 3 end secure the use of circuit of compositive stabilized voltage to go to the lavatory, the electron is made in often use, can you use change one's costume or dress to ⒃ ? ? Does entangled of Nai pregnant channel stand tall and upright? Book? Does 5 Bian of plinth of entangled of Jian of ぷ of grave of teach of You Pu of Qian of S rice Jian bark already Bin prostitute? All? Notice the 3 inputs that carry circuit of compositive stabilized voltage, output and ground connection end cannot receive a fault absolutely, burn out easily otherwise. General difference of voltage of the 3 the smallest inputs that carry circuit of compositive stabilized voltage, output is 2V about, cannot output stable voltage otherwise, should make voltage difference maintains commonly in 4-5V, namely classics transformer transformation, diode commutate, the voltage after capacitor filter wave should is worth than stabilized voltage a few taller. In applying actually, should be in 3 end are installed on circuit of compositive stabilized voltage enough big radiator (of course below the condition of small-power need not) . When temperature of stabilized voltage canal is exorbitant, stabilized voltage function will become poor, damage even. When the need in making one can be outputted 1. The regulated power supply of 5A above electric current, use paralell connection of circuit of a few 3 upright stabilized voltage to rise normally, make its the biggest output electric current is N 1. 5A, but need to notice when application: The circuit of compositive stabilized voltage that paralell connection uses should introduce the product of same manufacturer, same lot number, in order to assure the accord of parameter. Leave the surplus with have certain on output electric current additionally, in order to avoid the chain burn down that individual and compositive stabilized voltage brings about other circuit when circuit invalidation. In series of 78 ** , 79 ** 3 end in manostat most what often apply is TO-220 and TO-202 are enclosed two kinds. These two kinds of enclosed graphs and the serial number that cite a base, function that cite a base is shown like attached drawing place. The date citing a base in the graph tags a method is according to the potential that cite a base from tall after all tag orderly. Tag facilitating memory so. The ① that cite a base is highest potential, ③ foot is lowermost potential, ② foot be placed in the middle. Can see from inside the graph, be being pressed no matter still is negative pressure, ② foot all is output end. Controlling series to 78** , the input is highest potential, nature is ① foot, ground end is lowermost potential, namely ③ foot, if attached drawing place is shown. Right with series of 79** negative pressure, the input is lowermost potential, nature is ③ foot, and ground end is highest potential, namely ① foot, if attached drawing place is shown. In addition, still should notice, carbon fin always is linked together with the ③ foot of lowermost potential. Such is in in 78** series, carbon fin and ground photograph join, and in 79** series, carbon fin carries photograph join with the input however CNC Milling CNC Machining
