Description
TO-220
The L4941 is a three terminal 5V positive
regulators available in TO-220 and DPAK
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
DPAK
prolonging battery life. It employs internal current
limiting, antisaturation circuit, thermal shut-down
and safe area protection.
