Texas Instruments LM2940T-12-0 is a positive fixed 12V linear voltage regulator IC with a 1A output current capability. This device, housed in a TO-220-3 package, offers a low dropout voltage of 1V at 1A and supports input voltages up to 26V. Key protection features include over current, over temperature, reverse polarity, and short circuit protection. With a quiescent current of 10mA and a power supply rejection ratio (PSRR) of 66dB at 120Hz, the LM2940T-12-0 is suitable for applications in automotive, industrial control, and power supply systems requiring reliable voltage regulation. The device operates within an ambient temperature range of -40°C to 125°C.
