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

Verify the specific ordering suffix 'TRE1' confirms tape and reel packaging when sourcing. Confirm RoHS compliance status as indicated by the 'E1' or 'G1' designation in the final part number. Ensure the supplier provides the official datasheet DS41513 Rev. 2 for accurate electrical characteristics and absolute maximum ratings prior to integration.

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

Select this component for applications requiring high efficiency under low voltage differentials. The adjustable version allows precise voltage setting via external resistors. Consider the TO-252-5 package for thermal performance. Verify that the system's input voltage does not exceed the 13.5V maximum rating and that the required output current stays within the 1.5A limit.

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

This part belongs to the AZ39151 series of 1.5A ultra low dropout linear regulators. The series includes fixed 3.3V and 5.0V versions alongside the adjustable variant. All variants share the same core architecture, featuring low ground current and robust protection mechanisms suitable for consumer electronics and computer peripheral power supplies.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other 1.5A LDOs with similar dropout characteristics and TO-252-5 packages. Verify pinout compatibility, specifically the enable pin configuration and ground tab connection. Ensure replacement parts meet the same thermal resistance and reverse polarity protection requirements.
