L4922
DESCRIPTION
The L4922is a high currentmonolithic voltage regulator with very low voltage drop (0.70 V max at 1 A, TJ = 25 °C). The device is internally protected against load dumps transient of + 60V, reverse polarity, over- heatingand outputshort circuit : thanks toted for the automotive and industrial applications.
