DESCRIPTION L4800 series devices are voltage regulators with a very low voltage drop (typically 0.4V at full rated current), output current to 400mA, low quiescent current and comprehensiveon-chip protection.These devices are protected against load dump and field decay transients ± 60V, polarity reversal and overheating. A foldback current limiter protects against load short circuits. Available 9.2V,10V and12V versions (all = 25°C) these regulators are designed for automotive, industrial and consumer applications where low consumption is particularly important
