550 mA Ausgang LDO-Regler mit WDT und Spannungserkennung - BD4271FP2-C

Der BD4271FP2-C ist ein Spannungsregler für Automobile mit Watchdog-Timer und liefert einen Ausgangsstrom von 550 mA bei gleichzeitiger Begrenzung des Ruhestroms. Ein logisches HIGH am CTL-Stift aktiviert den LDO-Regler und ein LOW deaktiviert ihn und hält den Stromverbrauch niedrig. Ein Reset-Signal für eine Ausgangsspannung VO vom Typ 4,65 V wird erzeugt. Reset-Verzögerungszeit und Watchdog-Zeit (WDT) können durch den externen Kondensator programmiert werden.
