Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range (4.5V to 28V) to avoid damage or improper operation.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted using an external resistor. Refer to the datasheet for the specific formula to calculate the resistor values.

3. Output Current (IOUT):

   • The maximum continuous output current is 5A. Ensure the load does not exceed this limit to prevent overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 50μA with no load. This is important for low-power applications.

5. Efficiency (η):

   • The efficiency is typically 90% at 5V IN, 3.3V OUT, and 1A. Optimize the input and output voltages for maximum efficiency.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 150mV at 5V IN, 3.3V OUT, and 1A. Ensure the input voltage is sufficiently higher than the output voltage to maintain regulation.

7. Load Regulation (ΔVOUT):

   • The load regulation is typically 0.5% from 0 to 5A. This ensures stable output voltage under varying load conditions.

8. Line Regulation (ΔVOUT):

   • The line regulation is typically 0.05%/V over the input voltage range. This ensures stable output voltage with changes in input voltage.

9. PSRR (Power Supply Rejection Ratio):

   • The PSRR is typically 70dB at 100kHz. This helps in reducing noise from the input power supply.

10. Operating Temperature (TOPR):

    • The operating temperature range is -40°C to 125°C. Ensure the device is used within this range to avoid thermal stress.

11. Storage Temperature (TSTG):

    • The storage temperature range is -65°C to 150°C. Store the device in a suitable environment to prevent damage.

12. Thermal Shutdown (TSD):

    • The device has thermal protection that triggers at approximately 160°C. This prevents damage due to excessive heat.

Additional Notes:

• Always use appropriate decoupling capacitors on both the input and output sides to ensure stability and reduce noise.
• For high-power applications, consider adding heatsinks or other cooling solutions to manage thermal dissipation.
• Refer to the full datasheet for detailed application circuits and additional information.
