Overview
The LD1086DT25TR is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 1.5A. The device supports an input voltage range up to 30V and features a typical dropout voltage of 1.3V at full load, decreasing under lighter loads. It utilizes a DPAK (TO-252-3) surface-mount package and operates within a temperature range of -40°C to +125°C. Internal protections include overcurrent limiting and thermal shutdown.
Feature Summary
- Fixed 2.5V output voltage with ±1% tolerance at 25°C
- Low dropout performance ensuring high efficiency under varying load conditions
- Integrated thermal and current protection for robust operation
Applications
- Battery-powered systems requiring efficient voltage regulation
- Post-regulation stages in switching power supplies
- Embedded logic and peripheral power distribution
Procurement Notes
Verify the specific suffix 'DT' confirms the DPAK package and fixed 2.5V output configuration against the official datasheet. Confirm RoHS compliance status and check for end-of-life notices or alternative recommendations from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a stable 2.5V rail is required for digital logic or analog circuits. Ensure the input voltage remains within the 30V limit and that the thermal design accommodates the power dissipation associated with the DPAK package at 1.5A loads.
Part Context
This part belongs to the LD1086 family of 1.5A low-dropout regulators. The family offers both adjustable and fixed voltage options in various packages including TO-220, D²PAK, and DFN8. The LD1086 series is designed for applications needing better dropout performance than traditional PNP-based regulators.
Replacement Considerations
Check for pin-compatible alternatives within the same LD1086 family or newer generations from STMicroelectronics. Verify that any substitute maintains the 1.5A current rating, 2.5V fixed output, and DPAK footprint.
