LM2937ES-3.3/NOPB Description

Short technical summary and product information.

The LM2937ES-3.3/NOPB from Texas Instruments is a positive voltage regulator designed to supply up to 500 mA of load current. It utilizes a PNP power transistor, resulting in a low dropout voltage characteristic, typically 0.5V at full load.

 

This regulator is fully specified for operation between -40°C and 125°C. It includes internal protection features such as short circuit and thermal overload protection, as well as reverse battery protection and 60V input transient protection, making it suitable for demanding applications.

 

The device requires an output bypass capacitor for stability, and it is designed to be stable with output capacitor Equivalent Series Resistance (ESR) up to 3 Ω. The output is trimmed to 5% tolerance under all operating conditions.

 

Packaged in a TO-263-3 surface mount package, the LM2937ES-3.3/NOPB is well-suited for automotive and industrial control applications, including point-of-load regulation.
