The MP28301 is a monolithic power management unit containing a 700mA, high-efficiency, step-down, switching converter and a 100mA LDO regulator. The nA quiescent current provides extremely high efficiency when the load current is in the µA range. With the minimum input voltage as low as 2V, the MP28301 allows the system to operate directly from the battery. The constant-on-time (COT) control scheme provides fast transient response and high light-load efficiency, and requires minimal capacitance. The regulation is made tight by integrating an error amplifier to correct the output voltage. A 100mA LDO regulator provides easy system configuration with a clean output voltage. The CTRL pins control the on/off and output voltage selection functions. Fault protection features include under-voltage lockout (UVLO), over-current protection (OCP), and thermal shutdown. The MP28301 requires a minimal number of readily available, standard external components, and is available in a small QFN-12 (2mmx2mm) package.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP28301 is an authentic electronic component manufactured by Monolithic Power Systems, 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 MP28301 datasheet above.
Electronic component spot-market pricing for MP28301 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 MP28301 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.
