Features
Description
The L4940 series of three terminal positive
regulators is available in TO-220, TO-220FP and
D
voltages, making it useful in a wide range of
industrial and consumer applications. Thanks to
its very low input/output voltage drop, these
devices are particularly suitable for batteries
powered equipment, reducing consumption and
