Product Summary

The L4940V5 is a three terminal positive regulator. The L4940V5 is available in TO-220 and D2PAK package and with several fixed output voltages, making it useful in a wide range of industrial and consumer applications. Thanks to its very low input/output voltage drop, the device is particularly suitable for battery powered equipments, reducing consumption and prolonging battery life. Each type employs internal current limiting, antisaturation circuit, thermal shut-down and safe area protection.
