Texas Instruments LM2940S-5-0 is a positive fixed 5V linear voltage regulator with a 1A output current capability. This device features low dropout voltage of 1V at 1A, and offers robust protection against over current, over temperature, and short circuit conditions, along with reverse polarity protection. Operating across a temperature range of -40°C to 125°C, it is suitable for applications in automotive, industrial control, and consumer electronics. The TO-263 (DDPAK-3) surface mount package ensures efficient thermal management. Key specifications include a maximum input voltage of 26V, a quiescent current of 10mA, and a power supply rejection ratio (PSRR) of 64dB at 120Hz.
