Overview
The LD1086D2T25TR is a positive fixed linear low-dropout regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 1.5A. The device operates within an input voltage range up to 30V and features a maximum dropout voltage of 1.5V at full load. It incorporates internal protection mechanisms including overcurrent limiting and thermal shutdown. The component is housed in a D2PAK surface-mount package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrated overcurrent and thermal shutdown protection for enhanced reliability
- High power dissipation capability via D2PAK surface-mount packaging
- Low quiescent current consumption for efficient power management
Applications
- Battery-powered systems requiring stable 2.5V logic levels
- Portable equipment power distribution networks
- Embedded controller voltage regulation
Procurement Notes
Verify the specific suffix 'D2T' confirms the 2.5V fixed output variant, as the LD1086 family includes adjustable and other fixed voltage options. Confirm package integrity matches the D2PAK specification. Check manufacturer documentation for current lifecycle status, as this part may be discontinued or subject to last-time buy restrictions. Ensure RoHS compliance aligns with project requirements.
Selection Notes
Select this component when a precise 2.5V rail is required with high current capacity. Compare dropout characteristics against input supply variations to ensure regulation stability. Evaluate thermal resistance requirements based on expected load currents and ambient temperatures. Consider alternative packages if PCB space constraints differ from the D2PAK footprint.
Part Context
This part belongs to the LD1086 series of low-dropout regulators designed for general-purpose power management applications. The series offers various fixed and adjustable output voltages across different package types. The D2T25 suffix specifically denotes the 2.5V fixed output version in the D2PAK housing, distinguishing it from adjustable variants like the LD1086D2MTR.
Replacement Considerations
Direct substitutes include other LD1086 variants with identical pinouts but different output voltages if voltage adjustment is permissible. Verify electrical compatibility before swapping. No other specific replacement part numbers are confirmed in public documentation.
