AZ1085CD-2.5TRG1

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

The AZ1085CD-2.5TRG1 is a discontinued fixed positive low dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 2.5V output at up to 3A load current. It utilizes a TO252-2 (3/4/5) surface-mount package and operates within an input voltage range of 4.0V to 12V. The device features a maximum dropout voltage of 1.5V at full load, includes integrated thermal shutdown and current limiting protection, and maintains a typical ripple rejection ratio of 72dB at 120Hz.

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

This component is officially marked as obsolete and discontinued by the manufacturer. Verify final availability through authorized distributors or secondary markets. Confirm that the specific lot date code meets project requirements before procurement. Ensure all design-in documentation reflects the end-of-life status to prevent future supply chain disruptions.

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

Select this part only if the 2.5V fixed output aligns precisely with system requirements. Evaluate thermal dissipation capabilities in the target TO252-2 package under maximum load conditions. Consider alternative active LDO regulators if long-term supply continuity is critical for the product lifecycle.

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

The AZ1085C series represents a family of 3A low dropout linear regulators designed for high-efficiency power management applications. This specific variant belongs to the fixed-output subset, distinguishing it from adjustable versions that require external resistor networks. The series supports multiple standard packages including TO263 and TO252 configurations.

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

Public datasheets explicitly recommend using the AZ1084C series as a direct replacement for the AZ1085C line. Verify pinout compatibility and electrical specifications between the legacy AZ1085C and the recommended AZ1084C alternatives before implementation.
