LM2940CT-5.0 Description

Short technical summary and product information.

The LM2940CT-5.0 is a positive voltage regulator designed to source 1 A of output current with a low dropout voltage, typically 0.5 V at 1 A.

 

This regulator operates with an input voltage range of 6 V to 26 V. It includes features such as reverse battery protection, internal short circuit current limit, and mirror image insertion protection, making it suitable for vehicular applications. A quiescent current reduction circuit is incorporated, which lowers ground current when the input-output voltage differential exceeds approximately 3 V.

 

The LM2940CT-5.0 is available in a TO-220 package, designed for through-hole mounting. The operating temperature range is from 0 °C to 125 °C. The standard package quantity is 45 units per tube.
