Package
The LM1085IT-5.0 is a voltage regulator packaged in a TO-220 form factor. This package type is commonly used for power devices as it provides a good balance between size, heat dissipation capability, and ease of mounting on a heatsink or printed circuit board.
Pinout
The LM1085IT-5.0 is a low dropout voltage regulator with a fixed output voltage of 5.0V. It typically comes in a TO-220 package with three pins. The pin functions are as follows:
1. Pin 1 (Adjust/Ground): For the fixed version like the LM1085IT-5.0, this pin serves as the ground. It connects to the negative side of the load and the input supply.
2. Pin 2 (Output): This pin provides the regulated output voltage. For the LM1085IT-5.0, the output is fixed at 5.0V.
3. Pin 3 (Input): This is the input pin where an unregulated input voltage is applied. The device regulates this voltage down to the fixed 5.0V output.
The LM1085 is designed for applications requiring a lower dropout voltage and higher current capability. It can deliver up to 3A of output current with a dropout voltage of approximately 1.3V at full load.
