AZ1117D-1.5TRE1

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

The AZ1117D-1.5TRE1 is a positive fixed-output linear regulator from the AZ1117 series, manufactured by Diodes Incorporated. It provides a nominal output voltage of 1.5V with a maximum continuous output 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 incorporates a trimmed bandgap reference for high accuracy and includes on-chip thermal shutdown and current limiting protection. The component is housed in a TO252-3 surface-mount package.

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

Verify that the specific part number matches the required output voltage and package type before ordering. Confirm RoHS compliance status as per manufacturer documentation. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for any specific handling requirements related to moisture sensitivity upon receipt.

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 peripherals drawing up to 1A. Consider the thermal resistance of the TO252-3 package and the expected ambient temperature to ensure adequate heat dissipation without external heatsinks. Verify that the input voltage remains within the 15V maximum rating under all transient conditions.

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

This device belongs to the AZ1117 family of low dropout linear regulators designed for general-purpose power management applications. The 'D' suffix indicates the TO252-3 surface-mount package variant, while '1.5' specifies the fixed 1.5V output version. The 'TRE1' suffix denotes the tape and reel packaging format compliant with RoHS standards.

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

Diodes Incorporated recommends using the AZ1117C or AZ1117I series as direct replacements for new designs, as the original AZ1117 is not recommended for new design-in.
