In order to package the IC voltage regulator, a TO-220-3 case is used. On the Voltage regulator IC, there are 3 terminations that can be connected. As you can see, the regulator IC has a total of 3 pins. As far as the regulator type, it is a FIXED POSITIVE SINGLE OUTPUT LDO REGULATOR type. Generally, this voltage regulator IC can output 2.85V volts on a system level.
