LM25007MM/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25007MM/NOPB is a step-down switching regulator manufactured by Texas Instruments, originally developed under the National Semiconductor brand. It operates with an input voltage range of 9V to 42V and provides a single adjustable output from 2.5V to 37V. The device delivers up to 500mA of output current with a maximum switching frequency of 800kHz. It utilizes a synchronous buck topology without integrated synchronous rectifiers in this specific package variant context, housed in an 8-VSSOP package. The component supports operation across a junction temperature range of -40°C to 125°C.
