Overview
The LD1086V25 is a positive fixed linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 2.5 V with a maximum output current of 1.5 A. The device operates within an input voltage range up to 30 V and features a maximum dropout voltage of 1.2 V at full load. It includes internal protection against overcurrent and thermal overload. The component is housed in a TO-220 package and supports surface mount or through-hole installation depending on the specific variant, operating across a temperature range of -40°C to +125°C.
Feature Summary
- Provides stable fixed output voltage regulation
- Capable of delivering high output current up to 1.5 A
- Includes built-in thermal overload and current limiting protection
Applications
- General purpose power supply regulation
- Battery-powered systems requiring efficient voltage step-down
- Embedded electronics requiring stable 2.5 V logic rails
Procurement Notes
Verify the exact package type and pinout configuration before procurement, as variations exist within the LD1086 family. Confirm RoHS compliance status for the specific batch. Check for obsolescence notices as this component may be subject to lifecycle changes. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a fixed 2.5 V output is required with moderate current demands. Consider the thermal dissipation capabilities of the TO-220 package relative to the expected ambient temperature and load conditions. Compare dropout characteristics against the available input voltage headroom to ensure regulation stability under all operating scenarios.
Part Context
This part belongs to the LD1086 series of low-dropout regulators from STMicroelectronics. The series offers various fixed and adjustable output voltages with current ratings up to 1.5 A. The LD1086V25 specifically denotes the 2.5 V fixed output variant, designed for applications needing reliable linear regulation with integrated safety features.
Replacement Considerations
Direct substitutes include other LD1086 variants with compatible voltage and current ratings, such as LD1086D2T25TR for surface mount applications. Verify pin compatibility and thermal performance before substitution.
