The CMPWR330 is a dual input regulator with a fully integrated VAUX switch capable of delivering up to 400mA continuously at 3.3V. The input is taken from three independent voltage sources on a prioritized basis. Power is always taken in priority using the order of VCC, VSBY, and VAUX. When VCC, (5V) or VSBY is present, the device automatically enables the regulator and produces a stable 3.3V output at VOUT. When only VAUX (3.3V) is present, the device provides a low impedance direct connection (0.25Ω TYP.) from VAUX to VOUT. All the necessary control circuitry needed to provide a smooth and automatic transition between all three supplies has been incorporated. This allows the VCC input supply to be dynamically switched without loss of output voltage. The CMPWR330 is housed in an 8-pin SOIC package and is available with RoHS compliant lead-free finishing.
YG GROUP supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
CMPWR330 is an authentic electronic component manufactured by onsemi, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official CMPWR330 datasheet above.
Electronic component spot-market pricing for CMPWR330 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for CMPWR330 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
