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

Verify that the ordering suffix TRG1 corresponds to the Tape & Reel packaging format as specified in the official Diodes Incorporated documentation. Confirm the part number matches the industrial temperature range designation (I) and the specific 1.5V fixed output variant. Ensure compliance with RoHS and lead-free requirements if applicable to your manufacturing standards.

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

Select this component when a stable 1.5V rail is required for digital logic or peripheral circuits drawing up to 1A. The SOT-223 package is suitable for surface-mount applications where moderate thermal dissipation is sufficient. Consider the 1.2V dropout characteristic when designing for minimal voltage headroom between input and output sources.

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

This part belongs to the AZ1117I series of low dropout regulators designed for industrial temperature ranges (-40°C to +125°C). The 'H' suffix typically denotes the SOT-223 package variant within the Diodes Incorporated catalog, distinguishing it from TO-252 packages. The series is optimized for low voltage applications requiring fast transient response.

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

Direct pin-compatible substitutes include other AZ1117 variants with identical output voltages and package styles, such as the AZ1117CH-1.5TRG1 or AZ1117D-1.5TRE1, provided their electrical characteristics meet the system's dropout and current requirements.
