A Tape & Reel (TR) case is used to deliver the Voltage Regulated IC. A TO-263-3, D2Pak (2 Leads + Tab), TO-263AB case is used for packaging. As you can see, the IC chip has 2 terminations. Regulator IC chip's output type is Fixed. The electronic part implements 1 regulators in total. In this Regulator IC chip, the operating temperature of Surface Mount varies. 0°C~125°C degrees is the operating temperature of the Voltage Regulator IC. There is one output function configured for this voltage regulator IC, and that is Negative. As far as its current output is concerned, it stands at 1A. This chip has a total of 3 pins, which are arranged in a rectangular shape. It has 1 outputs to ensure that the performance of this regulator is prompt and sufficient. The dropout voltage of the regulator IC is 10 volts. For your information, this regulator's basic part number is MC79. There is a way of packing the regulator that is called TAPE AND REEL.
