The Texas Instruments LM2940T-5 is a 1-A low-dropout (LDO) voltage regulator. It features a wide input voltage range from 6 V to 26 V and provides a regulated output voltage with a typical dropout voltage of 0.5 V at 1 A. The device is capable of sourcing over 1 A of output current.
Key electrical specifications include a maximum output current of 1 A and a fixed output voltage option of 5 V, with other fixed options available from 5 V to 15 V. The regulator operates across a temperature range of -40°C to 125°C. It also offers features such as reverse battery protection and internal short-circuit current limiting.
Available in various packages including TO-263, SOT-223, WSON, and TO-220, the LM2940T-5 is suitable for surface mount applications. Its design includes a quiescent current reduction circuit that lowers ground current when the input-to-output voltage differential exceeds approximately 3 V, enhancing efficiency in certain operating conditions.
