LP3985IBL-2.6 Equivalent & Substitute Parts

Part Overview

The LP3985IBL-2.6 is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This device delivers 150mA output current at a fixed 2.6V output with a maximum dropout voltage of 0.1V at rated load. The regulator integrates over-current, over-temperature, and short-circuit protection features, making it suitable for low-power supply applications requiring stable voltage regulation.

The LP3985IBL-2.6 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.
