DESCRIPTION

L4800 series devices are voltage regulators with a

verylow voltage drop (typically 0.4V at fullrated cur-

rent), output current up to 400mA, low quiescent

currentandcomprehensiveon-chipprotection.The-

se devices are protected against load dump and

field decaytransients of ± 60V, polarity reversaland

overheating. A foldback current limiter protects

against load short circuits. Available in 5V, 8.5V,

9.2V,10V and12Vversions(all± 4%,T_I=25°C)the-

se regulatorsaredesignedforautomotive, industrial

and consumer applications where low consumption

is particularly important.

In automotiveapplications the L4805 is ideal for 5V

logicsuppliesbecauseitcan operateevenwhen the

batteryvoltagefallsbelow 6V. In batterybackupand

standbyapplications the low consumption of these

devices extends battery life.
