SGMICRO

SGMICRO (SG Micro Corp) is a Beijing-based maker of analog ICs — linear regulators, amplifiers, references and interface parts — for consumer, industrial and portable designs. The profiles here cover three power parts: two fixed-output low-dropout regulators from the SGM2036 family, the SGM2036-1.2YN5G/TR at 1.2 V in SOT-23-5 and the SGM2036-1.3YUDH4G/TR, plus the SGM431XN3LG/TR voltage reference. In this line the full ordering string carries the selection information: the digits after the family name fix the output voltage, and the suffix letters fix the package and tape-and-reel packing, so a near-identical string can be a different voltage or a different footprint. Quote the complete code in an RFQ and qualify the part against the SGMICRO datasheet for that code.

Sourcing notes for SGMICRO parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
