Pinout
1. VIN: This is the input voltage pin where the unregulated input voltage supply is connected.
2. Output (VOUT): This pin provides the regulated output voltage, which for the LM2596T-12 is fixed at 12V.
3. Ground (GND): This pin is the ground reference for the input and output voltages.
4. Feedback (FB): Typically used in the adjustable version of the LM2596, for the fixed version like the LM2596T-12, this pin is internally connected for a fixed output voltage and often not used externally.
5. ON/OFF: This pin is used to enable or disable the regulator. Connecting this pin to ground enables the regulator, while connecting it to a high level disables it, putting the regulator in a low-power shutdown mode.
This device is commonly used in applications requiring a fixed 12V output from a higher input voltage, providing efficient power conversion with minimal external components.
