LP2986IMM-5.0/NOPB Equivalent & Substitute Parts

Part Overview

The LP2986IMM-5.0/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications. This Power Management (PMIC) component delivers 200mA output current in an 8-VSSOP surface mount package. The device is Active status and widely used in embedded systems, consumer electronics, and industrial applications requiring stable 5V regulation from input sources up to 16V.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the product family. The LP2986, LP2987, and LP2988 series share identical electrical specifications and packaging, enabling direct substitution based on availability and inventory requirements.
