The MP103 provides an easy and low cost ACDC solution for less than 1W applications. It is an off-line linear regulator that delivers good efficiency while generating little EMI noise. It provides an easy solution to step down the AC line voltage to a regulated DC voltage. This off-line linear regulator replaces the conventional switching regulator, not needing a transformer or an inductor. Due to its simplicity, it offers an overall low BOM cost. MP103 delivers nearly two times the output power than the MP100 or MP100L by charging its VB capacitor with an external bipolar transistor. MP103 maximizes efficiency by minimizing the voltage drop between VB and VOUT, while only charging VB when VIN is less than approximately 32V. The MP103 enables the overall system to meet standby power requirements. MP103 offers rich protections, such as Thermal Shutdown (TSD), Over Temperature Protection (OTP), VB Over Voltage Protection (OVP), VB Short to GND Protection, Over Load Protection (OLP), Short Circuit Protection (SCP), MP103 is available in the SOIC8E 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.
MP103 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 MP103 datasheet above.
Electronic component spot-market pricing for MP103 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 MP103 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.
