Pinout
The LM2575HVSX-5.0 is a high-voltage version of the LM2575 series of step-down (buck) voltage regulators. It typically comes in a 5-pin TO-263 surface-mount package. Here's a brief overview of its pin functions:
1. Vin (Pin 1): This is the input pin where the supply voltage is provided.
2. Output (Pin 2): This pin provides the output voltage, which is regulated down to 5.0 volts in the LM2575HVSX-5.0 version.
3. Ground (Pin 3): This is the ground reference for both the input and output voltages.
4. Feedback (Pin 4): This pin is used to set the output voltage. The LM2575HVSX-5.0 has this internally set to regulate at 5.0 volts but in adjustable versions, it's connected to an external resistor divider to adjust the output.
5. ON/OFF (Pin 5): This pin enables or disables the regulator. Pulling this pin low shuts down the regulator to reduce the standby current.
These pins work together to efficiently convert a higher input voltage to a stable 5.0V output for various electronic applications.
