LD1086DT15R

Overview

The LD1086DT15R is a low-dropout positive voltage regulator manufactured by STMicroelectronics, belonging to the LD1086 series. It provides a fixed output voltage of 1.5 V with a maximum output current capability of 1.5 A. The device features a dropout voltage guaranteed at a maximum of 1.2 V at full load. It operates within an input voltage range up to 30 V and maintains an output tolerance of ±1% at 25 °C. The component utilizes a DPAK surface-mount package (TO-252) with three pins and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

Provides stable fixed output voltage with tight manufacturing tolerance for precision power supply applications
Ensures high efficiency as quiescent current flows into the load rather than being wasted internally
Integrates internal thermal overload protection and current limiting to safeguard against fault conditions

Applications

Battery-powered equipment requiring efficient linear regulation
Post-regulation stages in switching power supplies
General-purpose power management in embedded systems

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration when sourcing. Confirm that the fixed 1.5 V output variant matches the system requirement, as the LD1086 family includes adjustable versions. Ensure the DPAK package footprint aligns with the PCB layout design rules before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.5 V rail is required with up to 1.5 A load capacity. The DPAK package offers a balance between thermal dissipation and board space constraints compared to larger through-hole options. Consider the dropout characteristics relative to the minimum input voltage available in the design to ensure proper regulation under all load conditions.

Part Context

This part belongs to the LD1086 family of low-dropout regulators designed for high-current applications. The series is known for pin-to-pin compatibility with older standard adjustable regulators while offering superior performance metrics. The LD1086DT15R specifically represents the fixed 1.5 V output version in the DPAK surface-mount package format.
