L4921 - VERY LOWDROP ADJUSTABLE REGULATORS

Datasheet Summary

Description

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, polarity reversal and over heating.

VERY LOW DROP VOLTAGE ADJUSTABLE OUTPUT VOLTAGE FROM 1.25V TO 20V 400mA OUTPUT CURRENT LOW QUIESCENT CURRENT REVERSE VOLTAGE PROTECTION + 60/ − 60V TRANSIENT PEAK VOLTAGE PROTECTION SHORT CIRCUIT PROTECTION WITH FOLDBACK CHARACTERISTICS THERMAL SHUT-DOWN Pentaw att DESCRIPTION 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, polarity reversal and over heating. A foldbackcurrent limiter protectsagainstload short circuits. The outputvoltage is adjustablethrough an external divider from 1.25V to 20V.
