LM2940IMP-12/NOPB TI LDO Regulator | SOT-223-4 | 12V Output, 1A

Product Overview

The LM2940IMP-12/NOPB from Texas Instruments is a fixed-output low-dropout (LDO) voltage regulator designed to deliver a stable 12V output with a maximum current of 1A. Housed in a compact SOT-223-4 package, this device offers excellent line and load regulation, making it ideal for power-sensitive applications. Its low dropout voltage of typically 0.5V at full load ensures efficient operation even when the input voltage is close to the output. The LM2940 series is known for its reliability and thermal protection, making it a preferred choice for automotive, industrial, and telecommunications systems.
