    Products Detail

    L4972AD Overview


    It uses the Tube package in order to optimize the performance of this voltage regulator. During the development of this harley voltage regulator, 20 terminations were made. A SWITCHING REGULATOR type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. The harley voltage regulator is available as a 20-SOIC (0.295, 7.50mm Width) package to save space. The voltage regulator is configured with 1 outputs. As you can see, this DC DC switching regulator generates Adjustable output on its output pins. A Surface Mount mounting is required for this switching regulator. Voltage regulators should be operated at -40°C~150°C TJ temperature while operating. DC-DC switching regulators reach 100kHz~200kHz switching frequencies. Despite its low input voltage, this voltage regulator can operate. There is a voltage regulator maximum input voltage of 50V. This voltage regulator's peak reflow temperature is so high as to make it virtually indestructible. For operation, voltage regulator provides a nominal input voltage of 35V. The regulator voltage that you are looking at belongs to the subcategory Switching Regulator or Controllers. There is a DC/DC regulator in this family that belongs to the L4972 family. At 40V volts, voltage regulator can provide voltage. To operate the voltage regulator 12v, 20 pins are required. The output voltage of this voltage regulator 12v should at least be set at 5.1V volts at all times. Accordingly, dc to dc voltage regulator's maximum output current is 2A A. A maximum voltage of 40V can be obtained from the regulator voltage. Switching regulators such as this operate from voltages of 50V.

    L4972AD Features
