The LM2940CT-12/NOPB from Texas Instruments is a positive voltage regulator designed to provide a stable 12V output at up to 1A. It offers a low dropout voltage, typically 0.5V at 1A, and a maximum of 1V across its operating temperature range of 0°C to 125°C. This regulator includes features such as reverse battery protection, internal short circuit current limit, and thermal overload protection, making it suitable for demanding applications.
The device operates with an input voltage range of 6V to 26V. A quiescent current reduction circuit is incorporated, which lowers ground current when the input-output voltage differential exceeds approximately 3V. The LM2940CT-12/NOPB is packaged in a TO-220-3 through-hole configuration, with 45 units per tube.
Key electrical characteristics include a PSRR of 66dB at 120Hz. The regulator is designed for reliability and protection against common electrical faults, including mirror-image insertion.
This component is well-suited for applications requiring a reliable, fixed positive voltage supply with moderate current requirements and protection against transient conditions.
