AZ1084CD-1.5TRG1

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

The AZ1084CD-1.5TRG1 is a fixed positive low-dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal output voltage of 1.5V with a maximum load current capability of 5A. It operates within an input voltage range up to 12V and features a typical dropout voltage of 1.35V at full load. The device incorporates on-chip thermal limiting and current limiting circuits for protection against overload conditions. Packaged in a TO252-2 configuration (Options 3, 4, or 5) or TO252 Type CJ, it supports surface-mount assembly and functions reliably across a junction temperature range of 0°C to +125°C.

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

• Integrated thermal limiting and current limiting circuits protect the device from excessive junction temperatures and overloads.
• Compatible with low ESR ceramic capacitors for stable operation without requiring specific electrolytic types.
• Fixed output versions integrate internal adjust resistors to simplify circuit design and reduce external component count.

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

Verify the specific package option (TO252-2 Option 3, 4, or 5, or TO252 Type CJ) required for your PCB footprint, as the datasheet lists multiple mechanical variants under this part number. Confirm RoHS compliance status and ensure the supplier provides traceability documentation consistent with Diodes Incorporated standards before finalizing procurement orders.

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

Select this component when a fixed 1.5V rail is required with high current delivery up to 5A. Ensure the input voltage remains within the 12V limit and that the thermal management strategy accounts for the 1.5V maximum dropout voltage at peak load to prevent thermal shutdown during continuous operation.

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

This device belongs to the AZ1084C series of 5A low-dropout linear regulators. The series includes various fixed output voltages such as 1.8V, 2.5V, 3.3V, and 5.0V, as well as an adjustable version. All variants share common protection features and are available in standard TO252 packages suitable for surface-mount applications.

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

Cross-reference with other AZ1084C fixed 1.5V variants like AZ1084D-1.5TRG1 if different package options are needed. Verify pinout compatibility and thermal resistance characteristics when substituting with similar 5A LDOs from other manufacturers.
