Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
Texas Instruments LM2940IMPX-12 is a low-dropout voltage regulator designed for reliable power supply applications. This positive, fixed 12V output device delivers up to 1A of current with a maximum dropout voltage of 1V at 1A. It features robust protection circuitry including over current, over temperature, reverse polarity, and short circuit protection. The LM2940IMPX-12 operates from an input voltage range up to 26V and exhibits a power supply rejection ratio (PSRR) of 66dB at 120Hz. Housed in a SOT-223-4 (TO-261-4) surface-mount package and supplied on tape and reel, this component is suitable for demanding applications across automotive, industrial, and consumer electronics sectors, operating within an ambient temperature range of -40°C to 85°C.
