Description
The L4940 series of three-terminal positive
regulators is available in TO-220 and D²PAK
packages and with several fixed output voltages,
making it useful in a wide range of industrial and
consumer applications. Thanks to their very low
input/output voltage drop, these devices are
particularly suitable for battery-powered
equipment, reducing consumption and prolonging
battery-life. Each type employs internal current
limiting, anti-saturation circuit, thermal shutdown
and safe area protection.
