L4921 产品详情

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).

. 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
