Commonly used voltage regulator diode 1N4... Series, 1N5... Series, 1N7... Series, 2CW series, 2DW series, etc., three-end pressure regulator tube has 78... Series, 79... Series, etc.
Voltage regulator diode is A special diode that uses the reverse breakdown characteristic, mainly used in a variety of simple resistance and capacitance voltage regulator circuits or reference power supplies, such as the 1N4728 voltage regulator value of 3.3V, 1N4733\/A voltage regulator value of 5.1V, 1N4724A voltage regulator value of 12V.
The three-terminal voltage regulator is also called the three-terminal voltage regulator module, which is a high-precision high-power regulator composed of integrated circuits. Voltage regulator module is the voltage step-down treatment, and stabilized to a fixed value after output. For example, the three-terminal regulator block 7805 can reduce a voltage of less than 35v to a stable 5v output voltage. The three-end regulator block is divided into positive voltage regulator block 78 series and negative voltage regulator block 79 series.
