7530-1 voltage regulator triode pin function is voltage regulator diode when the negative electrode is connected to a high potential, a current limiting resistor example power supply is connected to a current limiting resistor, and then connected to a voltage regulator diode negative, voltage regulator diode positive ground, The use of voltage regulator diodes is to have unidirectional conductivity when the breakdown voltage of the regulator tube is lower than that of ordinary diodes. Turn on when the reverse voltage reaches the breakdown voltage of the regulator diode. If the reverse voltage of the regulator diode is lower than the resistance is very large. Equals and exceeds the conduction. The main function of voltage regulator diode is voltage regulator. Commonly used in regulated power supplies. In the circuit is always connected in reverse, the positive electrode of the regulator is connected to the negative electrode of the power supply
7530-1 Voltage regulator three feet are respectively input pin, output pin, a common ground pin.
