LM2940IMP-12 Description

Short technical summary and product information.

The Texas Instruments LM2940IMP-12 is a positive voltage regulator designed for applications requiring up to 1A of output current with a low dropout voltage. This device features a fixed 12V output and is suitable for vehicular applications due to its reverse battery protection and ability to withstand transients.

 

Key electrical characteristics include a typical dropout voltage of 0.5V at 1A and a maximum of 1V over the entire temperature range. It also incorporates a quiescent current reduction circuit, lowering ground current when the input-output voltage differential exceeds approximately 3V. The regulator is protected against over current, over temperature, reverse polarity, and short circuit conditions.

 

Packaged in a SOT-223-4 surface-mount format, the LM2940IMP-12 operates within an ambient temperature range of -40°C to 85°C. Its design includes features like output voltage trimming before assembly and P+ product enhancement testing, making it a robust choice for various power management needs.
