ADM1171-2AUJZ-RL7

Overview

The ADM1171-2AUJZ-RL7 is a high-voltage, low-dropout linear regulator manufactured by Analog Devices Inc. It provides a fixed 2V output voltage with a maximum load current of 500mA. The device operates from an input voltage range of 3.8V to 60V. It features a typical dropout voltage of 400mV at full load. The regulator includes internal protection mechanisms such as thermal shutdown and current limiting. It is housed in a compact 8-lead LFCSP package.

Feature Summary

• High input voltage capability up to 60V
• Low dropout performance for efficient regulation
• Integrated thermal and current protection

Applications

• Industrial sensor power supplies
• Automotive electronics systems
• Telecommunications equipment

Procurement Notes

Verify the specific suffix AUJZ-RL7 against the manufacturer's official datasheet to confirm the package type and reel quantity. Ensure the operating temperature range meets your system requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Check for any recent design changes or obsolescence notices from Analog Devices Inc.

Selection Notes

Select this component when a stable 2V supply is required from a higher voltage rail up to 60V. Consider its low dropout characteristic for applications where input voltage may vary close to the output level. Evaluate the thermal performance based on expected load currents and ambient temperatures. Compare it with other regulators in the ADM1171 family if different output voltages are needed.

Part Context

This part belongs to the ADM1171 series of high-voltage LDO regulators. The series offers various fixed output voltages to suit different application needs. The AUJZ package denotes an 8-lead LFCSP form factor. The RL7 suffix indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

Check for direct pin-to-pin replacements within the ADM1171 family with different output voltages. Verify compatibility with existing PCB layouts and thermal management solutions. Ensure substitute parts meet the same input voltage and current specifications.
