The LM2576-5.0WU is a fixed-output voltage regulator, specifically designed to provide a 5V output. It is a step-down (buck) switching regulator with a standard pin count of 5 pins. Here’s a brief overview of its pin functions:
1. VIN (Pin 1): This is the input pin where the unregulated voltage is supplied.
2. Output (Pin 2): This pin provides the regulated 5V output.
3. Ground (GND, Pin 3): This pin is the ground reference for the regulator, connected to the system ground.
4. Feedback (Pin 4): In the fixed version like the LM2576-5.0WU, this pin is internally connected and typically not used externally. It helps in maintaining the output voltage regulation.
5. ON/OFF (Pin 5): This pin allows the regulator to be turned on or off. Connecting it to ground enables the regulator, while connecting it to a voltage above 1.4V disables it.
