L7981TR Product Details

L7981TR Overview


This harley voltage regulator utilizes the Tape & Reel (TR) package for optimized performance. As you can see, this harley voltage regulator contains 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 voltage regulator is packaged in the 8-VFDFN Exposed Pad package. In this case, DC DC switching regulator has 1 outputs configured to it. There are output pins on this DC DC switching regulator that generate Adjustable output. The voltage regulator 12v fits the Surface Mount mounting hole. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. The switching frequency of this DC-DC switching regulator reaches 250kHz~1MHz. The output voltage of this voltage regulator (Min/Fixed) amounts to 0.6V volts. As a result of its peak reflow temperature, this voltage regulator is virtually indestructible. To meet the switching regulator operation requirements, a nominal input voltage of 12V is provided. The regulator voltage that you are looking at belongs to the subcategory Switching Regulator or Controllers. In the particular voltage regulators, the L7981 family is represented. The voltage DC DC switching regulator can provide is up to 28V volts. The switching regulator operation is carried out by 8 pins. For this switching regulator, we recommend keeping the output voltage at at least 600mV volts. For switching regulator maximum operation, dc to dc voltage regulator delivers 3A A. With a maximum output voltage of 28V, DC DC switching regulator has a very high efficiency. With 28V as the supply voltage, this DC-DC switching regulator will operate. A dc to dc voltage regulator's dc to dc voltage regulator's minimum supply voltage of 4.5V V ensures reliable performance.
