LD1086D2T50TR

Overview

The LD1086D2T50TR is a fixed-output low-dropout positive voltage regulator manufactured by STMicroelectronics. It provides a stable 5 V output with a maximum current capacity of 1.5 A. The device supports a maximum input voltage of 30 V and operates within an extended temperature range from -40 °C to +125 °C. Key electrical parameters include a typical dropout voltage of 1.3 V at full load, a maximum dropout of 1.5 V, and a line regulation of 10 mV. The unit features a TO-252-3 surface-mount package.

Feature Summary

• Integrated thermal overload and short-circuit protection mechanisms ensure operational safety under fault conditions.
• High line regulation performance maintains consistent output voltage stability against input supply variations.
• Low quiescent current consumption enhances overall system efficiency during operation.

Applications

• General-purpose power supply conditioning for electronic circuits
• Battery-powered equipment requiring efficient voltage regulation
• Embedded systems utilizing standard logic families

Procurement Notes

Verify the specific suffix 'DT' in the part number to confirm the fixed 5 V output configuration and TO-252-3 package type. Ensure compatibility with the target PCB footprint and thermal management requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Selection Notes

Select this component when a fixed 5 V rail is required with high current capability up to 1.5 A. The TO-252-3 package offers a balance between thermal dissipation and compact surface-mount form factor. Consider the 1.3 V typical dropout voltage when designing for minimum input-to-output differential constraints.

Part Context

This component belongs to the LD1086 series of low-dropout linear regulators designed for positive voltage applications. The series includes both adjustable and fixed output variants across multiple packages. The D2T designation specifically indicates the fixed voltage version housed in the DPAK/TO-252 form factor, distinguishing it from adjustable or larger package alternatives.

Replacement Considerations
