L4973D3.3-013TR Overview


This harley voltage regulator utilizes the Cut Tape (CT) package for optimized performance. This harley voltage regulator has 20 terminations. There is a SWITCHING REGULATOR type analog IC in this voltage regulator 12v that is used to convey analog signals. There is a 20-SOIC (0.295, 7.50mm Width) package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs on DC DC switching regulator. On its output pins, this adjusting voltage regulator generates Adjustable (Fixed) output. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~150°C TJ. 100kHz~300kHz is the switching frequency of this DC-DC switching regulator. 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 0.5V 3.3V. There is a maximum input voltage of 55V for this voltage regulator 12v. The peak reflow temperature of this regulator amounts to 250 to be essentially indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 24V. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. In the particular voltage regulators, the L4973 family is represented. There is a possibility that DC DC switching regulator can give voltage at 50V volts. There are 20 pins that are used for the operation of the voltage regulator 12v. Accordingly, dc to dc voltage regulator's maximum output current is 3.5A A. This DC-DC switching regulator operates from a supply voltage of 55V.
