L4973D5.1-013TR Overview
For optimal performance, this voltage regulator makes use of the Cut Tape (CT) package. In this voltage regulator, there are a total of 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 configured on this voltage regulator 12v. ICs such as this voltage regulator are capable of generating Adjustable (Fixed) outputs through their output pins. Switching regulators like this one can be mounted on the Surface Mount mounting system. The operating temperature should be kept at -40°C~150°C TJ when the voltage regulator 12v is in operation. A DC-DC switching regulator such as this one switches at 100kHz~300kHz. Regulator 8V can operate with dc to dc voltage regulator's minimum input voltage 8V. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 5.1V 5.1V. There is a voltage regulator maximum input voltage of 55V. As a result of the 250 peak reflow temperature, this regulator is essentially indestructible. For operation, voltage regulator provides a nominal input voltage of 24V. Listed under the subcategory of Switching Regulator or Controllers is this voltage regulator 12v. L4973 is a family of voltage regulators that belong to the DC/DC industry. A voltage of 5.1V volts can be produced by voltage regulator. During switching regulator operation, 20 pins are used. A maximum output current of 3.5A A is provided to meet the switching regulator operation requirements. The maximum output voltage of 50V makes DC DC switching regulator easy to operate. With 55V as the supply voltage, this DC-DC switching regulator will operate.
