LM2671N-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2671N-ADJ is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, housed in an 8-PDIP package. It operates as a buck converter with an adjustable output voltage range of 1.21 V to 37 V and supports up to 500 mA output current. The device integrates a 1-A internal switch and functions at a fixed switching frequency of 260 kHz. It features a low quiescent current of 2.5 mA and operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the package type matches your PCB footprint requirements, as this specific part number denotes through-hole mounting. Confirm that the adjustable output configuration aligns with your circuit design needs rather than fixed-voltage variants. Ensure compatibility with your required input voltage range and load current specifications before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole solution is preferred for prototyping or specific mechanical constraints exist. The adjustable output allows flexibility for various voltage rails. Consider the 260 kHz switching frequency for trade-offs between component size and efficiency. Verify that the 500 mA current limit meets the maximum load requirements of the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2671 series of SIMPLE SWITCHER regulators, designed for high-efficiency step-down applications. The 'N' suffix indicates the PDIP-8 through-hole package variant, distinguishing it from surface-mount options like the SOIC package. It is part of Texas Instruments' broader portfolio of monolithic switching regulators aimed at simplifying power supply design.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM2671M-ADJ for a surface-mount alternative. Verify if newer generations offer improved efficiency or different packaging options suitable for modern assembly processes.
