L7981ATR Overview
For optimal performance, this voltage regulator uses the Tape & Reel (TR) package. In this voltage regulator, 8 terminations are present. The harley voltage regulator is available as a 8-SOIC (0.154, 3.90mm Width) Exposed Pad package to save space. There are 1 outputs on DC DC switching regulator. There are output pins on this DC DC switching regulator that generate Adjustable output. The voltage regulator 12v fits the Surface Mount mounting hole. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~150°C TJ. A DC-DC switching regulator such as this one switches at 250kHz~1MHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 4.5V. There is a adjusting voltage regulator's voltage output (Min/Fixed) of 0.6V. A regulator with this 260 peak reflow temperature is essentially indestructible. For operation, switching regulator requires a nominal input voltage of 12V. I would like to point out that this voltage regulator belongs to the Switching Regulator or Controllers subcategory. This DC/DC regulator belongs to the L7981 family. Voltage of voltage regulator can be delivered at 28V volts. In order to operate voltage regulator, 8 pins are required. For this switching regulator, we recommend keeping the output voltage at at least 600mV volts. Switching regulator has a maximum output current of 3A A, which is sufficient to meet the requirements of operation. The maximum voltage of voltage regulator 12v DC DC switching regulator can produce is 28V, which is the highest available. An input voltage of 28V is used to operate this harley voltage regulator.
