LD1086D2T12TR

Overview

The LD1086D2T12TR is a positive fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 12 V output with a maximum continuous current of 1.5 A. The device operates within an input voltage range up to 30 V and features a typical dropout voltage of 1.3 V, reaching a maximum of 1.5 V at full load. It utilizes a TO-252-3 surface-mount package and supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Integrated thermal overload protection safeguards the device against excessive heat generation during operation.
• Internal current limiting circuitry prevents damage from output short circuits or overcurrent conditions.
• Low dropout characteristic enables efficient regulation with minimal input-to-output voltage differential.

Applications

• Battery-powered systems requiring stable voltage regulation
• General-purpose power supply sections in consumer electronics
• Embedded control units needing isolated logic power rails

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package degradation prior to soldering.

Selection Notes

Select this component when a fixed 12 V rail is required for high-current applications. The TO-252-3 package offers adequate thermal dissipation for moderate power loads. Consider alternative adjustable variants if flexible output voltages are needed instead of fixed configurations.

Part Context

This part belongs to the LD1086 series of low-dropout regulators designed for efficiency and reliability. The D2T suffix indicates a fixed 12 V output version housed in a TO-252-3 (DPAK) surface-mount package. It serves as a robust solution for converting higher input voltages to regulated 12 V outputs in compact designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin compatibility and thermal characteristics before considering any generic LDO replacements.
