Texas Instruments LM2940S-12 is a positive fixed 12V linear voltage regulator IC. This component delivers a stable 1A output current with a maximum input voltage of 26V. Featuring a low dropout voltage of 1V at 1A, it is designed for applications requiring efficient power regulation. The LM2940S-12 includes over-current, over-temperature, reverse polarity, and short-circuit protection for enhanced reliability. Its typical quiescent current is 10 mA. This device is commonly utilized in automotive, industrial, and consumer electronics sectors. Supplied in a TO-263 (DDPAK-3) surface-mount package, it is available in tube packaging. The regulator offers a Power Supply Rejection Ratio (PSRR) of 66dB at 120Hz.
