L4973D5.1 Overview


Using the Tube package, this voltage regulator optimizes the performance of the voltage regulator 12v. There are 20 terminations in this voltage regulator. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. Space savings are achieved by placing this voltage regulator in the 20-SOIC (0.295, 7.50mm Width) package. There are 1 outputs configured on this voltage regulator 12v. DC DC switching regulators like this one generate Adjustable (Fixed) outputs on their output pins to handle the power management. Switching regulators like this one can be mounted on the Surface Mount mounting system. As long as its operating temperature is -40°C~150°C TJ, dc to dc voltage regulator should perform well. This voltage regulator 12v reaches a switching frequency of 100kHz~300kHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 8V. The adjusting voltage regulator's output voltage (Min/Fixed) is 5.1V 5.1V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. As a result of DC DC switching regulator's design, it is designed to provide an input voltage of 24V for the purposes of operation. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. L4973 is a family of voltage regulators that belong to the DC/DC industry. Voltage can be produced at 50V volts by voltage regulator. 20 pins are used for switching regulator operation. In order for this switching regulator to work properly, the output voltage should be at least 5.1VV. A 3.5A A maximum output current is required to meet the switching regulator operation requirements. On the basis of 50V's maximal output voltage, DC DC switching regulator can be operated easily. An output voltage of 50V is provided by this regulator voltage. With a supply voltage of 55V, this harley voltage regulator works.
