AZ1085D-3.3TRG1

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

The AZ1085D-3.3TRG1 is a positive fixed-output low dropout linear regulator manufactured by Diodes Incorporated, designed for high-current applications up to 3A. It provides a stable 3.3V output with a maximum dropout voltage of 1.5V at full load. The device incorporates internal current limiting and thermal shutdown protection to ensure reliability under fault conditions. Packaged in the TO-252-2 (DPak) surface-mount format, it operates within a junction temperature range of 0°C to 125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated thermal shutdown circuitry prevents damage from excessive heat generation during operation.
• Built-in current limiting protects the regulator and load from short-circuit or overload events.
• Low dropout characteristic allows efficient regulation with minimal input-to-output voltage difference.

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

Verify that the component matches the specific Diodes Incorporated part number AZ1085D-3.3TRG1. Confirm the package type is TO-252-2 and the output voltage is fixed at 3.3V. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status as indicated by the suffixes. Cross-reference the manufacturer's latest datasheet to confirm active status and availability before finalizing procurement.

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

Select this regulator when a fixed 3.3V rail is required with up to 3A continuous load current. The TO-252-2 package offers a balance of thermal performance and space efficiency for surface-mount designs. Consider the 1.5V maximum dropout voltage when determining the minimum required input voltage to maintain regulation under peak load conditions.

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

This component belongs to the AZ1085 series of 3A low dropout linear regulators. The 'D' designation specifically identifies the TO-252-2 surface-mount package variant. The '3.3' indicates the fixed output voltage setting, while 'TRG1' denotes tape-and-reel packaging with green/lead-free specifications. This series is widely used in consumer electronics and industrial equipment requiring reliable linear power management.

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

Compatible substitutes include other 3A LDOs in the TO-252-2 package with a 3.3V fixed output, such as the LM317L variants or similar offerings from manufacturers like STMicroelectronics or Texas Instruments, provided they meet the 3A current and thermal requirements.
