Pinout
1. VIN (Input Voltage): This pin receives the input voltage, typically ranging from 4.5V to 40V, which the regulator will step down to the desired output voltage.
2. OUTPUT: This pin provides the regulated 3.3V output.
3. GROUND (GND): This pin is connected to the ground of both the input and output sides of the circuit.
4. FEEDBACK (FB): For the fixed 3.3V version, this pin is internally connected to the output and is not used externally. However, in adjustable versions of the LM2596, this pin is used to sense the output voltage for regulation.
5. ON/OFF (Shutdown): This pin is used to enable or disable the regulator. Pulling it low turns the regulator off, while connecting it to a voltage greater than 1.3V enables it.
The LM2596S-3.3 offers efficient performance with minimal external components, making it suitable for a wide range of power supply applications.
