L4973V3.3 Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. In this voltage regulator, there are a total of 18 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. There is a 18-DIP (0.300, 7.62mm) package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs on DC DC switching regulator. This DC DC switching regulator generates Adjustable (Fixed) output on its output pins. This voltage regulator 12v fits the Through Hole mounting. -40°C~150°C TJ should be the operating temperature when voltage regulator is operating. DC-DC switching regulators reach 100kHz~300kHz switching frequencies. A dc to dc voltage regulator's minimum input voltage of 8V is required for this voltage regulator to operate. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.5V 3.3V. An input voltage of 24V is required for switching regulator operation. This voltage regulator is included in the Switching Regulator or Controllers subcategory. As a member of the L4973 family of DC/DC regulators, this is a DC/DC regulator. The adjusting voltage regulator's output voltage is maintain at 50V. To operate the voltage regulator 12v, 18 pins are required. For this switching regulator, we recommend keeping the output voltage at at least 3.26V volts. A maximum output current of 3.5A A is available to meet the switching regulator operation requirements. DC DC switching regulator is able to operate in an easy way on the basis of the maximal output voltage of 50V. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 3.46V. With a supply voltage of 55V, this harley voltage regulator works.
