A Tape & Reel (TR) case is used to deliver the Voltage Regulated IC. A SOT-23 case is used for packaging. As you can see, the IC chip has 5 terminations. It has 1 outputs to ensure that the performance of this regulator is prompt and sufficient. It is important to note that this device has a FIXED POSITIVE SINGLE OUTPUT LDO REGULATOR regulator type. There is a way of packing the regulator that is called TAPE AND REEL.
