Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

This part number is officially obsolete and has been discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market channels rather than direct procurement. Confirm RoHS compliance status and verify that the specific lot date codes meet project requirements before acquisition. Ensure replacement components are evaluated for pin compatibility and electrical equivalence.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Designers requiring this functionality must select a compatible replacement from the same product family or a newer generation regulator. Verify that the substitute component maintains the required 3A output current capability and similar dropout characteristics. Check for updated package dimensions if mechanical constraints exist. Review the latest datasheets for any changes in thermal resistance or recommended capacitor values.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The AZ1085CS-ADJTRE1 is part of the broader AZ1085C series of low dropout linear regulators. This series includes fixed voltage options such as 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V alongside the adjustable variant. The 'CS' designation indicates the TO263 package type, while 'TRE1' specifies the tape-and-reel packaging and RoHS compliance. The series is designed for applications requiring high current delivery with minimal heat dissipation.
