The LM2940CSX-12 from Texas Instruments is a high-performance linear voltage regulator. It is capable of sourcing over 1A of output current with a typical dropout voltage of just 0.5V at 1A. The regulator features a fixed 12V output and a maximum input voltage of 26V.
Designed for reliability, the LM2940CSX-12 includes protection features such as reverse battery protection, internal short circuit current limit, and over-temperature protection. It also incorporates a quiescent current reduction circuit that lowers ground current when the input-output differential exceeds approximately 3V.
This component is supplied in a TO-263-3 (DDPAK/TO-263-3) surface mount package, making it suitable for various electronic designs. The operating temperature range is from 0°C to 125°C, ensuring performance in a variety of environments. The regulator also boasts a high Power Supply Rejection Ratio (PSRR) of 66dB at 120Hz.
