Instructions:

1. Power Supply Connection:

   • Connect the input voltage (V_IN) to the power supply within the specified range (2.7V to 5.5V).
   • Ensure the ground (GND) is properly connected.

2. Enable Control:

   • Apply a voltage greater than 1.2V to the enable pin (EN) to turn on the device.
   • To disable the device, apply a voltage less than 1.2V or leave the EN pin floating.

3. Load Connection:

   • Connect the load between the output (V_OUT) and ground (GND).
   • Ensure the load current does not exceed 1.5A to avoid overheating and potential damage.

4. Protection Features:

   • The device includes under-voltage lockout (UVLO) which turns off the device if the input voltage drops below 2.3V.
   • Over-voltage protection (OVP) will turn off the device if the output voltage exceeds 6.0V.
   • Thermal shutdown (TSD) will activate if the device temperature reaches 150°C to prevent damage.

5. Operating and Storage Conditions:

   • Operate the device within the specified temperature range (-40°C to 85°C) for optimal performance.
   • Store the device in a temperature range of -65°C to 150°C.

6. Layout Considerations:

   • Use short, wide traces for power and ground connections to minimize inductance and resistance.
   • Place bypass capacitors close to the input and output pins to filter noise and ensure stable operation.

7. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper soldering techniques to ensure reliable connections and avoid thermal stress.
