L4920 regulators equivalent, very lowdrop adjustable regulators.
where low consumption is particularly important. In battery backup and standby applications the low consumption of these.
The L4920 and L4921 are adjustable voltage regulators with a verylow voltage drop (0.4V typ. at 0.4A Tj = 25°C), low quiescent current and comprehensive on-chip protection. Thesedevices are protectedagainst load dump and field decay transients, polar.
