L4921规格书详情
DESCRIPTION
The L4920 and L4921 are adjustable voltage regulator swith a very low voltage drop(0.4V typ.at 0.4A Tj = 25°C), low quiescent current and comprehensive on-chip protection.
These devices are protected against load dump and field decay transients, polarity reversal and over heating.
A foldback current limiter protects against load short circuits.
The output voltage is adjustable through an external divider from 1.25V to 20V. The minimum operating input voltage is 5.2V (TJ = 25°C).
