Instructions for Using AOZ1948AI

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Connect the input voltage to the VIN pin.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 0.6V and 5.0V.
   • Use external resistors to set the desired output voltage according to the formula: [ V_ = V_ left(1 + fracright) ] where ( V_ ) is the feedback reference voltage (typically 0.6V).

3. Output Current (IOUT):

   • The device can provide up to 3A of continuous output current.
   • Ensure that the load does not exceed this limit to avoid overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 40μA under normal operating conditions.
   • This value helps in assessing the efficiency of the regulator in low-power applications.

5. Shutdown Current (ISD):

   • When the shutdown pin (SHDN) is pulled low, the device enters a low-power mode with a typical shutdown current of 1μA.
   • Use this feature to conserve power when the regulator is not in use.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation.
   • At full load (3A), the dropout voltage is typically 0.4V.

7. PSRR (Power Supply Rejection Ratio):

   • The PSRR indicates the ability of the regulator to reject ripple from the input voltage.
   • At 1kHz, the PSRR is typically 60dB, which means the output voltage will have minimal ripple even if the input voltage has significant noise.

8. Load Transient Response:

   • The load transient response is the change in output voltage when the load current changes rapidly.
   • The typical change in output voltage is ±3% when the load current changes from 0A to 3A.

9. Line Transient Response:

   • The line transient response is the change in output voltage when the input voltage changes rapidly.
   • The typical change in output voltage is ±3% when the input voltage changes from 2.7V to 5.5V.

10. Operating Temperature Range (TJ):

    • The device is designed to operate within a temperature range of -40°C to 125°C.
    • Ensure that the ambient temperature and heat dissipation are managed to keep the junction temperature within this range.

11. Storage Temperature Range (TSTG):

    • The device can be stored in temperatures ranging from -65°C to 150°C.
    • Avoid exposing the device to extreme temperatures for extended periods to prevent degradation.

Additional Notes:

• Always ensure proper PCB layout and thermal management to optimize performance and reliability.
• Use bypass capacitors on both the input and output to filter out high-frequency noise and improve stability.
• Refer to the datasheet for detailed information on pin configurations, package types, and additional specifications.
