AZ1084D-3.3TRE1

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

The AZ1084D-3.3TRE1 is a discontinued low dropout positive voltage regulator manufactured by Diodes Incorporated, belonging to the AZ1084 series. It provides a fixed 3.3V output with a maximum load current of 5A and a typical dropout voltage of 1.3V at full load. The device features on-chip thermal limiting and current limiting circuits for protection. It operates within an input voltage range up to 12V and supports junction temperatures from 0°C to +125°C. The component is housed in a TO-252-2 (3) surface-mount package and is supplied in tape and reel format.

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

Designers should evaluate the AZ1084C series as the designated replacement family for new designs. Ensure that the replacement component matches the required output voltage, current capacity, and thermal dissipation requirements. Review updated datasheets for any changes in pinout configurations or electrical characteristics before finalizing the schematic.

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

The AZ1084 series represents a line of 5A low dropout linear regulators designed for applications requiring stable voltage delivery under heavy loads. The D suffix indicates the TO-252-2 package variant, while TRE1 specifies the tape and reel packaging format. This specific model was widely used in consumer electronics and computing hardware prior to its obsolescence notification.

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

Diodes Incorporated explicitly recommends using the AZ1084C series as the direct substitute for this discontinued product. Verify that the selected AZ1084C variant maintains identical pinout compatibility and electrical specifications to ensure seamless integration into existing PCB layouts without redesign.
