DESCRIPTION
L4800series devices are voltage regulatorswith a
verylowvoltagedrop(typically0.4Vat fullratedcur-
rent), output current up to 400mA, low quiescent
currentandcomprehensiveon-chipprotection.The-
se devices are protected against load dump and
fielddecaytransientsof
±
60V,polarityreversaland
overheating. A foldback current limiter protects
against load short circuits. Available in 5V, 8.5V,
9.2V,10Vand12Vversions(all
