Pinout

The LM2596R-12 is a step-down voltage regulator integrated circuit with a fixed output voltage of 12V. It typically comes in a TO-220 package and features 5 pins, each serving a distinct function:
1. Vin (Input Voltage): This pin receives the input voltage, which can be as high as 40V. It is where the step-down process begins.

2. GND (Ground): This pin is connected to the ground of the circuit. It serves as the reference point for the regulator's output voltage.
3. Vout (Output Voltage): This pin provides the regulated output voltage, which is fixed at 12V for the LM2596R-12 version.
4. Feedback (FB): This pin is used internally for the feedback loop to maintain the output voltage at a stable level. In fixed versions like the LM2596R-12, this pin is connected internally.
5. ON/OFF: This pin is used to enable or disable the regulator. Applying a voltage (typically above 1.3V) will turn off the regulator, while grounding or leaving it open enables the output.
The LM2596R-12 is commonly used for efficient power conversion in various electronic applications.
