Package
The LM1084IT-5.0 is a fixed voltage regulator in a TO-220 package type. It is designed to provide a 5.0V output with a current capability of up to 5A. The TO-220 package is a standard through-hole package known for its ability to dissipate heat efficiently, making it suitable for power applications.
Pinout
The LM1084IT-5.0 is a low dropout (LDO) linear voltage regulator designed to provide a fixed output voltage of 5.0V. It is commonly used to maintain a steady voltage level for electronic components. The device typically comes in a TO-220 package and has three pins:
1. Input (Pin 1): This pin is connected to the unregulated input voltage. The input voltage must be higher than the desired output voltage by a value greater than the dropout voltage specific to the LM1084IT series.
2. Output (Pin 2): Provides the regulated 5.0V output. It is connected to the load that requires the stabilized voltage.
3. Ground (Pin 3): The common return path for both the input and output voltage, serving as the reference point for the voltage regulation process.
This configuration ensures that the LM1084IT-5.0 efficiently maintains a consistent 5V output despite variations in the input voltage or load conditions.
