LD1086BV

Overview

The LD1086BV is a low-dropout positive voltage regulator from STMicroelectronics, capable of delivering up to 1.5 A of output current. It features an adjustable output voltage range and operates within an input voltage window of 2.85 V to 30 V. The device guarantees a maximum dropout voltage of 1.2 V at full load. It includes internal thermal overload protection and current limiting. The component supports operation across a temperature range of -40 °C to +125 °C and utilizes a TO-220 package.

Feature Summary

• Provides high output current capability of up to 1.5 A
• Ensures stable regulation with low dropout voltage characteristics
• Incorporates built-in thermal overload and current limit protection

Applications

• General-purpose linear power supply circuits
• Battery-powered equipment requiring efficient voltage regulation
• Embedded systems power management modules

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and package type. Ensure the procurement source provides valid traceability for RoHS compliance status. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential lifecycle changes before finalizing orders.

Selection Notes

Select this component when a robust 1.5 A linear regulator is required for positive voltage applications. Consider the thermal performance in the TO-220 package relative to the expected ambient temperature and heat dissipation requirements. Verify that the input voltage remains within the specified 30 V maximum limit during all operating conditions.

Part Context

This component belongs to the LD1086 series of low-dropout regulators designed for high-current applications. The BV suffix typically denotes a specific package variant, often associated with through-hole mounting options like TO-220. This series is engineered for stability without external compensation capacitors, simplifying circuit design for power management tasks.

Replacement Considerations

Consult official substitution lists for equivalent LDO regulators with matching current ratings and voltage limits. Verify pin compatibility and thermal resistance values before replacing. Generic replacements may differ in dropout voltage specifications or protection feature implementations.
