L4973V5.1 Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. In this voltage regulator, 18 terminations are present. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. Space savings are achieved by placing this voltage regulator in the 18-DIP (0.300, 7.62mm) package. In this case, DC DC switching regulator has 1 outputs configured to it. On the output pins of this DC DC switching regulator, there is a Adjustable (Fixed) output generated. Through Hole-mounting is compatible with this switching regulator. -40°C~150°C TJ should be the operating temperature when voltage regulator is operating. A DC-DC switching regulator such as this one switches at 100kHz~300kHz. Input voltage 8V is the dc to dc voltage regulator's minimum input voltage required for operation of the voltage regulators. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 5.1V 5.1V. Voltage regulator is designed to provide a nominal input voltage of 24V to meet the operation requirements. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. DC/DC regulators of this type are part of the L4973 family of voltage regulator 12vs. Voltage regulator is capable of giving voltage at 50V volts. The switching regulator operation of the system is controlled by 18 pins. For this switching regulator, we recommend keeping the output voltage at at least 5.1V volts. The maximum output current reaches 3.5A A to meet the switching regulator operation requirements. The maximal output voltage of 50V allows adjusting voltage regulator for simple operation. An output voltage of 50V is provided by this regulator voltage. 55V is the supply voltage for this DC-DC switching regulator.
