LM25005MH Equivalent & Substitute Parts

Part Overview

The LM25005MH is a buck switching regulator IC from Texas Instruments designed for step-down voltage conversion applications. It delivers positive adjustable output from 1.225V to 37V with a maximum output current of 2.5A, operating across an input voltage range of 7V to 42V. The device is housed in a 20-PowerTSSOP surface mount package and operates across the industrial temperature range of -40°C to 125°C.

The LM25005MH carries a Last Time Buy product status, indicating limited availability. Identifying equivalent substitute parts ensures design continuity and supply chain flexibility for applications requiring this topology and performance specification.
