The package is in a TO-92 case. As you can see, the IC chip has 3 terminations. Adjustable is the IC Voltage Regulator's output type. There is an output of 100mA at the moment. In total, this chip consists of 3 pins and is divided into two groups. Depending on the chip, 3 pins may be available. The temperature should be below 125°C when you use the IC voltage regulator. The chip is operated at a maximum operating temperature of -40°C. A system basis, this IC regulator can output -37V volts. In this part, each channel has a specific job to do to keep the system running.
