E-L4973V3.3 Product Details

E-L4973V3.3 Overview


For optimal performance, this voltage regulator uses the Tube package. In this voltage regulator, there are 18 terminations. 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. For space-saving purposes, this voltage regulator is available in the 18-DIP (0.300, 7.62mm) package. The voltage regulator is configured with 1 outputs. As you can see, this DC DC switching regulator generates Adjustable (Fixed) output on its output pins. Switching regulators like this one can be mounted on the Through Hole mounting system. As long as its operating temperature is -40°C~150°C TJ, dc to dc voltage regulator should perform well. DC-DC switching regulators reach 100kHz~300kHz switching frequencies. Voltage regulators like this one can operate at least with 8V as the dc to dc voltage regulator's minimum input voltage. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 0.5V 3.3V. There is a maximum input voltage of 55V for this voltage regulator 12v. For operation, switching regulator requires a nominal input voltage of 24V. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. DC/DC regulators such as this one belong to the L4973 family of products. Voltage can be produced at 50V volts by voltage regulator. There are 18 pins used for switching regulator operation. To meet its operating requirements, dc to dc voltage regulator can deliver a maximum output current of 3.5A A. With 55V as the supply voltage, this DC-DC switching regulator will operate.
