LDO-Regler für sehr niedrigen Ruhestrom - BD733L2FP3-C

Die BD7xxL2EFJ/FP/FP2/FP3-C sind Regler mit niedriger Sättigungsspannung. Die absolute maximale Spannung beträgt 50 V und die Genauigkeit der Ausgangsspannung ± 2 %, 200 mA Ausgangsstrom und 6 µA (typ.) Stromverbrauch. Diese Regler eignen sich ideal für Anwendungen mit direktem Anschluss an die Batterie und niedrigem Stromverbrauch. Die Keramikkondensatoren können als Phasenkompensationskapazität des Ausgangs eingesetzt werden. Die ICs haben außerdem Überstromschutz, um den Halbleiter vor Schäden durch Kurzschluss zu schützen. Die integrierte thermische Abschaltung schützt den Halbleiter vor Überhitzung durch Überlast.
