The LM2576HVT-5.0 is a step-down voltage regulator from the LM2576 series, specifically designed to provide a fixed 5.0V output. It comes in a TO-220 package and has 5 pins. Here are the pin functions:
1. Pin 1 (Input): This is the input pin where the unregulated DC voltage is applied. It can accept a voltage range typically up to 60V for the HVT (High Voltage) version.
2. Pin 2 (Output): This pin provides the regulated 5.0V output. It connects to the load that requires the stabilized output voltage.
3. Pin 3 (Ground): The ground pin is the common ground reference for the input and output voltages.
4. Pin 4 (Feedback): This pin is used for feedback and regulation. In fixed output versions like the 5.0V, it is internally set to maintain the desired output and typically connected to the output.
5. Pin 5 (ON/OFF): This is the shutdown pin. It allows the device to be turned on and off with an external signal. Pulling this pin low enables the regulator, while a high level shuts it down.
