The Texas Instruments LM2940CS-5.0 is a linear voltage regulator designed to provide a stable 5V output at up to 1A of current. It features a low dropout voltage, typically 0.5V at 1A, and a maximum dropout of 1V across its operating temperature range of 0°C to 125°C.
This regulator is suitable for applications requiring a fixed positive output voltage. It offers protection features including over current, over temperature, reverse polarity, and short circuit protection. The device is available in a surface mount DDPAK/TO-263-3 package.
Key electrical characteristics include a maximum input voltage of 26V, a typical quiescent current of 10mA, and a PSRR of 54dB at 120Hz. The regulator has a typical accuracy of 5% and requires a minimum load capacitance of 22µF.
