DESCRIPTION
The L4920 and L4921 are adjustable voltage regu-
lators with a verylow voltage drop (0.4V typ. at 0.4A
Tj = 25°C), low quiescent current and comprehen-
sive on-chip protection.
Thesedevices are protectedagainst load dump and
field decay transients, polarity reversal and over
heating.
A foldbackcurrent limiter protectsagainstload short
circuits.
The outputvoltage is adjustablethrough an external
divider from 1.25V to 20V. The minimum operating
input voltage is 5.2V (TJ = 25°C).

ORDERING NUMBERS : L4920 (Pentawatt)
L4921 (Minidip)
These regulators are designed for automotive, in-
dustrial and consumer applications where low con-
sumption is particularly important.
In battery backup and standby applications the low
consumption of these devices extends battery life.
