Pinout

The LM2596T-5.0 is a step-down voltage regulator with a fixed output of 5.0 volts. It comes in a TO-220 package and typically has 5 pins. The pin functions are as follows:
1. Pin 1 (IN): Input voltage pin. This is where the unregulated input voltage is supplied.
2. Pin 2 (GND): Ground pin. It serves as the ground reference for the device and is connected to the ground of the input and output circuits.
3. Pin 3 (OUT): Output voltage pin. This is where the regulated 5.0V output is obtained.
4. Pin 4 (FB): Feedback pin. In the fixed version like the LM2596T-5.0, this pin is internally connected to maintain the fixed output voltage.
5. Pin 5 (ON/OFF): Enable pin. It is used to turn the regulator on or off. It can be connected to a logic level to control the operation of the regulator.
The LM2596T-5.0 is widely used in applications requiring a simple and efficient step-down converter for a fixed 5V output.
