L4973D3.3 Overview


It uses the Tube package in order to optimize the performance of this voltage regulator. This harley voltage regulator has 20 terminations. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. In order to save space, this harley voltage regulator is available in the 20-SOIC (0.295, 7.50mm Width) package. There are 1 outputs configured on the voltage regulator. On its output pins, this adjusting voltage regulator generates Adjustable (Fixed) output. There is a switching regulator that is compatible with the Surface Mount mounting. -40°C~150°C TJ should be the operating temperature when voltage regulator is operating. 100kHz~300kHz is the switching frequency of this DC-DC switching regulator. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 0.5V 3.3V. 250 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. Voltage regulator is designed to provide a nominal input voltage of 24V to meet the operation requirements. There is a subcategory of this regulator voltage called Switching Regulator or Controllers. DC/DC regulators of this type are part of the L4973 family of voltage regulator 12vs. The voltage DC DC switching regulator can provide is up to 50V volts. In order to operate voltage regulator, 20 pins are required. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 500mV. Switching regulator has a maximum output current of 3.5A A, which is sufficient to meet the requirements of operation. DC DC switching regulator is able to operate in an easy way on the basis of the maximal output voltage of 50V. Using this voltage regulator 12v, you will be able to get the maximum output voltage of 50V. This DC-DC switching regulator operates from a supply voltage of 55V. A dc to dc voltage regulator's dc to dc voltage regulator's minimum supply voltage of 8V V ensures reliable performance.
