DESCRIPTION

The L4940 series of three terminal positive

regulators 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, these devices are

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.
