    Products Detail

    L7981 Overview


    For optimal performance, this voltage regulator makes use of the Tube package. In this voltage regulator, there are a total of 8 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. In order to save space, this harley voltage regulator is available in the 8-VFDFN Exposed Pad package. There are 1 outputs configured on this voltage regulator 12v. There are output pins on this DC DC switching regulator that generate Adjustable output. Surface Mount-mounting is compatible with this switching regulator. The operating temperature should be kept at -40°C~150°C TJ when the voltage regulator 12v is in operation. This DC-DC switching regulator has a switching frequency of 250kHz~1MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 4.5V. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 0.6V. 260 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 12V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. The L7981 family of DC/DC regulators includes this DC/DC regulator. The voltage DC DC switching regulator can produce is 28V volts. There are 8 pins that are used for the operation of the voltage regulator 12v. The maximum output current reaches 3A A to meet the switching regulator operation requirements. 28V is the supply voltage for this DC-DC switching regulator.
