LM2671MX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2671MX-ADJ/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments. It integrates a 0.45A internal switch and operates at a fixed switching frequency of 260kHz. The device accepts an input voltage range from 6.5V to 40V and provides an adjustable output voltage between 1.21V and 37V. It delivers a maximum output current of 500mA with a typical quiescent current of 2.5mA. The component is housed in an 8-SOIC package (PowerPAD) and supports operation over an extended temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MX' against official Texas Instruments documentation to confirm it denotes the SOIC-8 PowerPAD package variant. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status as indicated in the latest datasheet revision. Cross-reference the part number with authorized distributors to avoid obsolete or counterfeit inventory.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 260kHz switching frequency is required to minimize passive component size. It is suitable for applications needing an adjustable output up to 37V with moderate current demands. Consider the thermal performance of the SOIC-8 PowerPAD package for heat dissipation requirements. Compare input voltage ranges and efficiency curves against alternative regulators in the LM267x family.
