Instructions for Use:

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage (V_OUT):

   • The output voltage is fixed at 3.3V. No external resistors are required for voltage adjustment.

3. Output Current (I_OUT):

   • The device can provide up to 400mA of output current.
   • For higher current requirements, consider using a different regulator or parallel configuration.

4. Quiescent Current (I_Q):

   • The quiescent current is very low at 1.5μA, making it suitable for battery-powered applications.

5. Dropout Voltage (V_DO):

   • The dropout voltage is 300mV at full load (400mA) with an input voltage of 5V.
   • Ensure the input voltage is at least 300mV higher than the output voltage to maintain regulation.

6. Load Regulation:

   • The load regulation is 0.5%, indicating minimal change in output voltage as the load varies from 0 to 400mA.

7. Line Regulation:

   • The line regulation is 0.05% per volt, ensuring stable output voltage even with variations in input voltage.

8. Ripple Rejection:

   • The ripple rejection is 60dB at 1kHz, effectively reducing input ripple on the output.

9. Operating Temperature (T_OP):

   • The device operates reliably from -40°C to 85°C.
   • Avoid operating in environments outside this temperature range to prevent performance degradation or failure.

10. Storage Temperature (T_STG):

    • Store the device between -65°C and 150°C to ensure long-term reliability.

11. Mounting and Handling:

    • Handle the device with care to avoid static discharge and physical damage.
    • Follow standard soldering procedures to ensure proper mounting on the PCB.

12. Capacitors:

    • Use a 1μF ceramic capacitor on the input and a 1μF ceramic capacitor on the output for stability and filtering.
    • Place these capacitors as close as possible to the device to minimize noise and improve performance.
