LM1086CS-2.5/NOPB

Overview

The LM1086CS-2.5/NOPB is a fixed positive low dropout linear regulator manufactured by Texas Instruments, delivering a maximum output current of 1.5 A with a fixed output voltage of 2.5 V. It operates within an input voltage range of 2.6 V to 30 V and features a typical dropout voltage of 1.3 V at full load. The device is housed in a surface-mount D2PAK (TO-263) package with three pins. It supports an operating temperature range from 0°C to +125°C and includes internal current limiting and thermal shutdown protection for robust performance.

Feature Summary

Fixed 2.5 V output voltage configuration
High current capability up to 1.5 A
Low dropout voltage operation
Integrated thermal and current protection

Applications

Point-of-load regulation in embedded systems
Battery-powered equipment requiring stable 2.5 V rails
General-purpose power supply circuits

Procurement Notes

Verify the specific suffix 'CS' corresponds to the commercial temperature grade (0°C to +125°C) and D2PAK package variant. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance as per manufacturer specifications. Ensure the fixed 2.5 V output matches the target circuit requirements before procurement.

Selection Notes

Select this component when a fixed 2.5 V rail is required with high current capacity. Compare against adjustable variants if voltage flexibility is needed. Consider the D2PAK package for thermal management and PCB space constraints. Verify input voltage headroom to ensure dropout voltage remains within acceptable limits under maximum load conditions.

Part Context

This part belongs to the LM1086 series of 1.5A low dropout regulators. It shares core architecture with other fixed and adjustable variants in the family, differing primarily in output voltage setting and package type. The CS suffix denotes the commercial temperature range and surface-mount packaging, distinguishing it from through-hole or industrial grade alternatives.
