AZ1117D-5.0TRE1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AZ1117D-5.0TRE1 is a positive fixed-output linear regulator from the AZ1117 series, manufactured by Diodes Incorporated. It provides a stable 5.0V output with a maximum continuous current of 1A. The device operates within an input voltage range up to 15V and features a typical dropout voltage of 1.15V at full load. It includes integrated thermal shutdown and trimmed current limiting for protection. The component is housed in a TO252-2 (3) surface-mount package and supports an operating junction temperature range from -40°C to +125°C.

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

Verify the specific suffix TRE1 corresponds to the Tape & Reel packaging format as defined in the manufacturer's ordering information. Confirm that the D suffix indicates the TO252-2 package type compatible with your PCB footprint. Ensure compliance requirements match the RoHS E1 designation listed in the datasheet specifications.

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

Select this component when a fixed 5V rail is required for loads up to 1A in space-constrained designs. The TO252-2 package offers a balance between thermal performance and board area. Consider the 1.15V dropout characteristic to ensure sufficient headroom between input supply and the 5V output under all operating conditions.

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

This part belongs to the AZ1117 family of low dropout linear regulators produced by Diodes Incorporated. The series includes adjustable versions and various fixed voltage options available in multiple power packages such as SOT223, SOT89, and TO263. The AZ1117D variant specifically utilizes the TO252-2 form factor for surface mount assembly.

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

The datasheet explicitly recommends using AZ1117C or AZ1117I series parts instead of the standard AZ1117 for new designs.
