L4940xx
Very low drop 1.5 A regulator
Features
Precise 5, 8.5, 10, 12 V outputs
Low dropout voltage (450 mV typ. at 1 A)
Very low quiescent current
Thermal shutdown
Short circuit protection
Reverse polarity protection
Description
The L4940 series of three terminal positive
regulators is available in TO-220, TO-220FP and
D2PAK packages 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 batteries
powered equipment, reducing consumption and
prolonging battery life. Each type employs internal
current limiting, antisaturation circuit, thermal
shut-down and safe area protection.
