LD1086DT18TR

Overview

The LD1086DT18TR is a positive fixed low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 1.8 V output with a maximum load 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 at full load, reaching a maximum of 1.5 V. It incorporates internal thermal overload protection and current limiting. The component is housed in a surface-mount DPAK (TO-252-3) package and supports operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

Provides a fixed 1.8 V regulated output suitable for digital logic power supplies
Delivers high continuous output current capability up to 1.5 A
Integrates built-in thermal shutdown and safe operating area protection

Applications

Power supply sections for microcontrollers and embedded processors
Battery-powered equipment requiring efficient voltage regulation
General-purpose positive voltage regulation in consumer electronics

Procurement Notes

Verify the exact suffix against official STMicroelectronics documentation to confirm pinout compatibility and package variations. Ensure the procurement channel sources genuine components to avoid counterfeit risks associated with power management ICs. Cross-reference the specific date code and lot number with manufacturer traceability records if required for quality assurance protocols.

Selection Notes

Select this component when a fixed 1.8 V rail is required with moderate current demands up to 1.5 A. It is appropriate for designs where input voltages may vary significantly but must remain below the 30 V absolute maximum rating. Consider the thermal performance of the DPAK package relative to the expected ambient temperature and PCB copper area for heat dissipation.

Part Context

This part belongs to the LD1086 series of low-dropout regulators designed for efficiency and stability. The series offers various fixed output voltages and adjustable versions to support diverse power management needs. The DT suffix indicates the specific surface-mount DPAK packaging variant optimized for automated assembly processes.
