2-Kanal CMOS-LDO-Regler mit variablen Schritten - BD7004NUX

Diese Serie enthält 2-Kanal und 3-Kanal-Typen, durch die sich die Notwendigkeit eines Eingangskondensators erübrigt, was zu einer weiteren Platzeinsparung führt. Der BD7004NUX integriert eine 2-Kanal-Schaltung, liefert 9 Ausgangsstrukturen (basierend auf den Einstellungen der 2 Eingangsklemmen (P1 und P2)) und wird im Kompaktgehäuse angeboten, ideal für kompakte Geräte.

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