LM1086CS-2.85/NOPB

Overview

The LM1086CS-2.85/NOPB is a fixed positive low-dropout linear regulator manufactured by Texas Instruments, delivering a maximum output current of 1.5 A with a precise fixed output voltage of 2.85 V. It operates within an input voltage range of 2.6 V to 29 V and features a typical dropout voltage of 1.3 V at full load. The device utilizes a D2PAK-3 (TO-263-3) surface-mount package and supports an extended operating temperature range from -40 °C to +125 °C.

Feature Summary

Integrates zener-trimmed band gap reference for high accuracy
Includes internal current limiting and thermal shutdown protection
Compatible with industry-standard pinouts for easy replacement

Applications

Point-of-load regulation in embedded systems
Battery-powered equipment requiring efficient step-down conversion
General-purpose power supply circuits

Procurement Notes

Verify the specific suffix 'CS' corresponds to the TO-263-3 package variant when sourcing. Confirm that the '-NOPB' designation ensures compliance with RoHS standards and absence of halogenated flame retardants. Cross-reference datasheets to ensure the fixed 2.85 V output matches the target circuit requirements exactly.

Selection Notes

Select this component when a stable 2.85 V rail is required with up to 1.5 A capacity. Ensure the input voltage remains above the minimum threshold while accounting for dropout characteristics under load. Verify thermal management capabilities are sufficient for the expected ambient conditions and power dissipation levels.

Part Context

This part belongs to the LM1086 family of low-dropout regulators, designed as a drop-in replacement for the LM317 adjustable regulator. The series offers both fixed and adjustable output options, providing flexibility for various power management applications while maintaining high efficiency and reliability.
