1-Kanal 150 mA CMOS-LDO-Regler - BH12PB1WHFV

ROHM's LDO Regler für tragbare Geräte haben originale CMOS Prozesse für niedrigen Verbrauch und hohe Präzision. ROHM's CMOS LDO Regler mit automatischer Energiesparfunktion zeichnen sich durch automatische Umschaltung bei Schwankungen des Ausgangssignals aus, durch die optimale Ausgangssignale erzielt werden. Der Energieverbrauch wird minimiert, indem der Strom während des Standbys auf nur 2µA gekürzt wird. Schnellschaltung auf die optimale Stromzufuhr wird während des Betriebs automatisch vollzogen. Zusätzlich wurde eine Sanftanlauffunktion eingebaut, dass den einfließenden Strom während des Startens auf die Kondensatorleistung minimiert. Die ICs sind in einem kompakten HVSOF5 Gehäuse erhältlich und enthalten einen eingebauten Kühlkörper.

* Dieses Produkt entspricht der STANDARD-Güte und wird nicht für Fahrzeugteile empfohlen.
