Pinout
1. Vin: This is the input voltage pin where the power supply voltage is applied. It can accept a wide range of input voltages.
2. Output: This is the regulated output voltage pin, providing the fixed 5.0V output.
3. Ground (GND): This pin is the ground reference for the input and output voltages.
4. Feedback (FB): Though in the fixed version this pin is internally connected to maintain the fixed output voltage, in adjustable versions, it is used to set the output voltage.
5. ON/OFF (Enable): This is the shutdown pin, which can be used to enable or disable the regulator. When brought low, it puts the device in a low-power shutdown mode.
This configuration allows the LM2574HVM-5.0 to efficiently step down higher input voltages to a stable 5.0V output with minimal external components.
