LM3671MF-3.3/NOPB TI DC-DC Converter | SOT-23-5 | 3.3V Output, 600mA

Product Overview

The LM3671MF-3.3/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed 3.3V output from a 2.7V to 5.5V input supply. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low quiescent current and high efficiency. With a maximum load current of 600mA, it is suitable for powering low-voltage digital circuits, sensors, and wireless modules.
