$2.62

Categories:

The LM2940T-5.0 by Texas Instruments is a robust linear voltage regulator, encapsulated in the widely recognized TO-220-3 package. This component is adept at delivering a stable 5V output, designed for through-hole mounting which ensures reliable mechanical and electrical connections. It operates over an extended temperature range from -40°C to +125°C, making it suitable for demanding environments.

Characterized by its ease of use and minimal external components, the LM2940T-5.0 stands out for its low dropout voltage, enhancing the system’s efficiency by allowing operations closer to the battery’s discharge end-point. This feature is particularly beneficial for automotive applications, with the device ensuring stable operation even under fluctuating conditions like those found in vehicle power supplies.

Being part of a class of voltage regulators that trades off higher efficiency against the more complex switch-mode regulators, this component finds its utilization not only in automotive but also in other industrial applications, where reliable linear regulation is paramount. This includes but is not limited to power management solutions for embedded systems, where stability and simplicity are the main criteria.

Despite its status as “Not For New Designs,” the LM2940T-5.0 remains a reliable choice for legacy systems or ongoing projects where compatibility and proven performance outweigh the need for the latest technology advancements. Its packaging in tubes facilitates storage and handling for mass manufacturing processes or hand assembly alike.
