AZ1085CD-3.3TRG1

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

The AZ1085CD-3.3TRG1 is a discontinued positive linear regulator from the AZ1085C series, manufactured by Diodes Incorporated. It provides a fixed 3.3V output with a maximum load current of 3A and a maximum dropout voltage of 1.5V at full load. The device features an input voltage range up to 12V, thermal shutdown protection, and current limiting. It is housed in a TO252-2 (3) surface-mount package and operates within a junction temperature range of 0°C to +125°C.

• Motherboard power distribution networks

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

This component is officially marked as obsolete and discontinued by the manufacturer. Procurement must rely on secondary market distributors or surplus inventory channels. Verify part authenticity and storage conditions carefully due to potential long-term availability gaps. Confirm that the specific TO252-2 (3) package variant matches design requirements before acquisition.

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

Designers should evaluate the AZ1084C series as the recommended replacement for this discontinued regulator. The alternative offers similar functionality but requires verification of pinout compatibility and thermal characteristics. Ensure that the new selection meets all original electrical specifications, including dropout voltage and current limits, without requiring significant PCB layout modifications.

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

The AZ1085CD-3.3TRG1 belongs to the AZ1085C family of low dropout linear regulators. This series is characterized by high efficiency and reliable performance in power management applications. The 'CD' suffix indicates the TO252-2 package type, while '3.3' denotes the fixed output voltage. The 'TRG1' suffix specifies tape and reel packaging with RoHS compliance.

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

Diodes Incorporated explicitly recommends using the AZ1084C series as a substitute for the discontinued AZ1085C parts. Engineers must verify that the AZ1084C variants match the required output voltage and package dimensions to ensure seamless integration into existing designs.
