Instructions for Using ADP3605A3:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 18V.
   • Use appropriate input filtering capacitors to reduce noise and ripple.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted from 0.8V to 17.5V using external resistors.
   • Use the formula ( V_ = 0.8 left(1 + fracright) ) to set the desired output voltage.

3. Output Current (IOUT):

   • The device can provide up to 3A of continuous output current.
   • Ensure proper heat dissipation if operating at high output currents.

4. Quiescent Current (IQ):

   • The quiescent current is typically 1.2mA under no-load conditions.
   • This low quiescent current helps improve efficiency in low-power applications.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 0.3V at full load.
   • Ensure the input voltage is at least 0.3V higher than the output voltage to maintain regulation.

6. Load Regulation:

   • The load regulation is typically 0.2% over the load range from 0mA to 3A.
   • This ensures stable output voltage under varying load conditions.

7. Line Regulation:

   • The line regulation is typically 0.01% per volt.
   • This indicates excellent stability of the output voltage with changes in input voltage.

8. Power Supply Rejection Ratio (PSRR):

   • The PSRR is typically 70dB at 100Hz.
   • This helps in rejecting input voltage variations and maintaining a clean output.

9. Thermal Shutdown (TSD):

   • The device will shut down if the junction temperature exceeds 160°C.
   • Ensure adequate cooling to prevent thermal shutdown.

10. Operating Junction Temperature (TJ):

    • The operating junction temperature range is from -40°C to 125°C.
    • Ensure the device operates within this temperature range to avoid damage.

11. Storage Temperature (TSTG):

    • The storage temperature range is from -65°C to 150°C.
    • Store the device in a dry environment within this temperature range.

By following these parameters and instructions, you can effectively use the ADP3605A3 in your power supply designs.
