L7981 Product Details

L7981 Overview


There is an optimized performance in this voltage regulator because it utilizes the Tube package. This harley voltage regulator has 8 terminations. The type of analog IC that this voltage regulator is equipped with is SWITCHING REGULATOR. For space-saving purposes, this voltage regulator is available in the 8-VFDFN Exposed Pad package. A total of 1 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. There is a switching regulator that is compatible with the Surface Mount mounting. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. A DC-DC switching regulator such as this one switches at 250kHz~1MHz. The voltage regulator can be operated with a voltage as low as 4.5V as an input voltage. 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. An input voltage of 12V is required to meet the requirements of the switching regulator operation. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. As part of the L7981 series of regulators, the voltage regulators can be found. Voltage can be produced at 28V volts by voltage regulator. There are 8 pins used for switching regulator operation. For switching regulator maximum operation, dc to dc voltage regulator delivers 3A A. Switching regulators such as this operate from voltages of 28V.
