Instructions for ADM709LARZ-REEL

1. Input Voltage Setup:

   • Ensure the input voltage is within the operating range of 3.0V to 16V. The regulator will not function outside this range.

2. Output Voltage Configuration:

   • The device provides a fixed output voltage of 5.0V. No external components are required for setting this voltage.

3. Quiescent Current Consideration:

   • The quiescent current is typically 70μA when no load is applied and the input voltage is 5V. This should be considered in low-power applications.

4. Dropout Voltage Management:

   • The dropout voltage is typically 1.2V at an output current of 100mA. Ensure that the input voltage exceeds the output voltage by at least this amount to maintain regulation.

5. Load and Line Regulation:

   • For optimal performance, monitor load regulation (change in output voltage with load) and line regulation (change in output voltage with input voltage). These parameters ensure stable output under varying conditions.

6. Ripple Rejection:

   • The device offers good ripple rejection, which helps in filtering out noise from the input supply. At 120Hz, it can reject up to 70dB of ripple.

7. Thermal Protection:

   • The thermal shutdown feature activates at approximately 160°C to protect the device from overheating. Ensure adequate heat dissipation in your design.

8. Short-Circuit Protection:

   • The device limits the short-circuit current to approximately 280mA, protecting against potential damage due to short circuits.

9. Handling and Storage:

   • Store in a dry environment and handle with care to avoid damage. Follow ESD precautions as recommended for sensitive electronic components.

10. Mounting:

    • Mount on a PCB using standard surface mount technology. Ensure all connections are secure and follow the manufacturer's guidelines for layout and clearance.
