The LM2575S-5.0 is a fixed-output voltage regulator with a pin count of 5. It is designed to provide a 5V output with a maximum output current of 1A. Here is a concise description of its pin functions:
1. VIN: This is the input pin where the unregulated voltage is supplied. The LM2575S can accept input voltages ranging from approximately 7V to 40V.
2. GND: This pin serves as the ground reference for the device. It should be connected to the system ground.
3. VOUT: This is the output pin where the regulated 5V output is available. It is capable of supplying up to 1A of continuous current.
4. Feedback (FB): This pin is used for adjustable versions, but in the fixed version like the LM2575S-5.0, it is internally connected to the internal resistive voltage divider that sets the output voltage.
5. ON/OFF: This pin is used to enable or disable the regulator. When this pin is connected to ground, the regulator is enabled; when a voltage above approximately 1.3V is applied, the regulator is turned off.
