The Texas Instruments LM2940SX-12 is a positive fixed 12V linear voltage regulator with a 1A output current capability. This component is housed in a TO-263 (DDPAK-3) surface-mount package, suitable for applications requiring efficient thermal management. It features an input voltage range up to 26V and a maximum dropout voltage of 1V at 1A. Protection features include over current, over temperature, reverse polarity, and short circuit protection. With a quiescent current of 10mA, this regulator is designed for reliable operation across an extended temperature range of -40°C to 125°C. The LM2940SX-12 finds application in automotive, industrial, and consumer electronics sectors where stable voltage regulation is critical. It is supplied on a Tape & Reel (TR) for automated assembly.
