LD1085D2M25R

Overview

The LD1085D2M25R is a fixed positive linear voltage regulator manufactured by STMicroelectronics, delivering a constant 2.5V output at up to 3A load current. It operates within an input voltage range of 3.4V to 30V and features a maximum dropout voltage of 1.5V at full load. The device incorporates internal thermal overload and current limit protection mechanisms. It utilizes a D2PAK-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

Provides stable fixed positive voltage regulation with high output current capability
Integrates comprehensive protection against overcurrent conditions and excessive junction temperatures
Designed for low dropout operation to maintain regulation under minimal input-output voltage differentials

Applications

General-purpose power supply conditioning circuits
Biasing stages in portable electronic devices
Pre-regulation for switching converter inputs

Procurement Notes

Verify the specific suffix 'D2M25R' to confirm the 2.5V fixed output variant and D2PAK-3 packaging configuration. Ensure compatibility with standard surface-mount reflow profiles. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when a reliable 2.5V rail is required for loads up to 3A. Evaluate thermal dissipation capabilities based on the expected ambient temperature and PCB copper area. Verify that the minimum input voltage remains above the dropout threshold across all operating conditions.

Part Context

This part belongs to the LD1085 family of low-dropout regulators designed for high-current applications. The series offers various fixed output voltages and adjustable versions to support diverse system architectures. It serves as a robust alternative to older three-terminal adjustable regulators while maintaining pin-to-pin compatibility.
