L4800 series devices are voltage regulators with a
very low voltage drop (typically 0.4V at full rated cur-
rent), output current up to 400mA, low quiescent
current and comprehensiveon-chip protection.The-
se devices are protected against load dump and
field decay transients of ± 60V, polarity reversal and
overheating. A foldback current limiter protects
against load short circuits. Available in 5V, 8.5V,
9.2V,10V and 12V versions (all± 4%, TI = 25°C) the-
se regulators are designed for automotive, industrial
and consumer applications where low consumption
is particularly important.

In automotive applications the L4805 is ideal for 5V
logic supplies becauseit can operateeven when the
batteryvoltage falls below 6V. In battery backup and
standby applications the low consumption of these
devices extends battery life.
