AZ1085CS2-ADJTRE1

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

The AZ1085CS2-ADJTRE1 is an obsolete adjustable positive low dropout linear regulator manufactured by Diodes Incorporated. It provides a maximum output current of 3A with a typical dropout voltage of 1.3V at full load and a maximum of 1.5V. The device features on-chip thermal shutdown, bandgap reference, and current limiting circuitry. 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 TO263-2 (D2PAK) surface-mount package.

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

This specific part number is officially marked as obsolete and discontinued by the manufacturer. Verification of availability should focus on surplus or secondary market channels rather than standard distribution. Confirm RoHS compliance status and verify that the TO263-2 package dimensions match the target PCB footprint before procurement.

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

Designers requiring this functionality must evaluate alternative components due to the discontinuation status. Ensure replacement parts support the required 3A output current and maintain similar dropout characteristics. Verify that the new selection accommodates the same thermal management requirements and fits the existing TO263-2 land pattern without redesigning the enclosure.

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

The AZ1085C series represents a family of 3A low dropout linear regulators designed for applications requiring stable voltage regulation under high load conditions. This specific variant utilizes the TO263-2 package, which integrates the ground connection through the exposed tab for improved thermal dissipation. The series includes both fixed and adjustable output options to accommodate various system voltage requirements.
