Procurement Notes

Verify the exact suffix '2.8' indicates the specific fixed output voltage configuration during procurement. Confirm the 16-TSSOP_EP package type matches your PCB footprint requirements. Ensure compatibility with the specified 2.7 V to 15.0 V input range for your system design. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when a combined solution for multiple regulated outputs and a load switch is required. It is suitable for designs prioritizing low power consumption and minimal PCB area. Consider the specific current ratings of 50 mA, 300 mA, and 800 mA to ensure adequate drive capability for all connected loads. Verify thermal performance within the operating temperature range for your application environment.

Part Context

This part belongs to the ADP5310 series of integrated power management units. It consolidates multiple power functions typically handled by discrete components. The series is known for high integration levels aimed at simplifying power supply design. It serves as a direct replacement for separate buck converter and LDO combinations in space-constrained applications.

Replacement Considerations

Check for pin-compatible alternatives within the same Analog Devices portfolio if lead times are critical. Ensure substitute parts maintain similar input voltage ranges and output current capabilities. Verify that any replacement also offers integrated load switch functionality to preserve system simplicity.
