The LM2596SX-3.3 is a step-down voltage regulator designed to provide a fixed 3.3V output. It comes in a TO-263 package and typically has five pins. Here are the pin functions:
1. Vin: This is the input voltage pin where the unregulated input voltage is supplied. It typically accepts a range of 4.5V to 40V.
2. Output: This pin provides the regulated output voltage, which is fixed at 3.3V for this specific variant of the LM2596 series.
3. Ground (GND): This pin is connected to the ground of both the input and output voltages.
4. Feedback (FB): Although not used in the fixed-voltage version like the LM2596SX-3.3, this pin is generally used in adjustable versions to adjust the output voltage by connecting it to a resistor divider network.
5. ON/OFF: This pin is used to enable or disable the regulator. Pulling it low disables the device, while leaving it open or pulling it high enables the device.
