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

Verify the specific suffix TRE1 corresponds to the SOT223 package and tape & reel packing configuration as listed in the official Diodes Incorporated ordering information. Confirm that the H designation indicates the correct temperature grade and marking ID EH17A. Ensure compliance with RoHS directives by checking the E1 suffix documentation. Cross-reference the datasheet revision DS36736 Rev. 5-3 for accurate electrical specifications before integration.

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

Select this part when a stable 5.0V rail is required for loads up to 1A with minimal voltage drop. The SOT223 package offers a balance of thermal performance and board space efficiency compared to larger through-hole options. Consider the thermal resistance characteristics for heat dissipation requirements in enclosed environments. Verify input voltage stability remains within the 15V maximum rating under all operating conditions.

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

This component belongs to the AZ1117 series of three-terminal low dropout regulators manufactured by Diodes Incorporated. The series includes adjustable and various fixed voltage versions available in multiple power packages such as SOT89, TO220-3, and TO263. The AZ1117H variant specifically denotes the SOT223 package option with defined thermal and electrical characteristics suitable for surface-mount applications.

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

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