PAK packages, 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. It employs internal current
limiting, antisaturation circuit, thermal shut-down
and safe area protection.
