Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 2.7V to 6.5V.
   • Connect the input voltage to the VIN pin.

2. Output Voltage (VOUT):

   • The ADM705ANZ provides a fixed output voltage of 3.3V.
   • Connect the load to the VOUT pin.

3. Output Current (IOUT):

   • The device can provide up to 150mA of continuous output current.
   • Ensure the load does not exceed this current limit to avoid overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 40μA when no load is applied.
   • This low quiescent current makes the device suitable for battery-powered applications.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 300mV at full load (150mA).
   • Ensure the input voltage is at least 300mV higher than the output voltage to maintain regulation.

6. Line Regulation:

   • The line regulation is typically 0.05% over the input voltage range.
   • This indicates that the output voltage remains stable even with variations in the input voltage.

7. Load Regulation:

   • The load regulation is typically 0.1% from no load to full load.
   • This ensures that the output voltage remains stable as the load changes.

8. Ripple Rejection:

   • The ripple rejection is typically 70dB over a frequency range of 10Hz to 100kHz.
   • This helps in filtering out input voltage noise and providing a clean output.

9. Operating Temperature:

   • The device operates reliably over a temperature range of -40°C to 125°C.
   • Ensure the ambient temperature is within this range to avoid thermal issues.

10. Storage Temperature:

    • The device can be stored in temperatures ranging from -65°C to 150°C.
    • Store the device in a dry, cool place to prevent damage.

Additional Notes:

• Capacitors:
  • Place a 1μF ceramic capacitor close to the VOUT pin to ensure stability.
  • A 1μF ceramic capacitor on the VIN pin is recommended to filter input noise.
• PCB Layout:
  • Use a good PCB layout with short traces and wide power planes to minimize inductance and improve performance.
• Thermal Management:
  • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
