L4941
VERY LOW DROP 1A REGULATOR
s LOW DROPOUT VOLTAGE (450mV Typ. at
1A)
s VERY LOW QUIESCENT CURRENT
s THERMAL SHUTDOWN
s SHORT CIRCUIT PROTECTION
s REVERSE POLARITY PROTECTION
DESCRIPTION
The L4941 is a three terminal 5V positive
regulators available in TO-220, TO-220FP and
D²PAK 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.
