Instructions for Use

1. Input Connection:

   • Connect the input voltage (V_IN) to the VIN pin.
   • Ensure the input voltage is within the specified range (2.7 V to 5.5 V).

2. Output Connection:

   • Connect the load to the V_OUT pin.
   • The output voltage is fixed at 3.3 V.

3. Ground Connection:

   • Connect the ground (GND) pin to the common ground of the system.

4. Capacitors:

   • Place a 1 μF ceramic capacitor between VIN and GND as close as possible to the device.
   • Place a 1 μF ceramic capacitor between V_OUT and GND as close as possible to the device.

5. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
   • The thermal shutdown feature will activate if the junction temperature exceeds 160°C.

6. Operating Temperature:

   • The device is designed to operate within a junction temperature range of -40°C to 125°C.
   • Store the device in an environment with a temperature range of -40°C to 150°C.

7. Handling Precautions:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow proper soldering techniques to prevent thermal shock and mechanical stress.

8. Testing:

   • Before final assembly, test the device under typical operating conditions to ensure it meets the required specifications.
