LM2596S-5.0(HG)

LM2596S-5.0(HG) is the official ordering code of the HGSEMI (Huaguan Semiconductor) LM2596 fixed 5 V step-down regulator in TO-263-5, supplied on tape at 800 pieces per reel in the maker’s ordering information. Marketplace listings write this part as LM2596S-5.0/TR — the /TR is the marketplace’s packing notation, not HGSEMI’s code; the (HG) suffix is how the maker itself marks its device, and it is the string to quote in an RFQ. Every figure on this page is HGSEMI’s own: output held between 4.8 V and 5.2 V across a 7 V to 40 V input and a 0.2 A to 3 A load, efficiency of 80 % typical at 12 V in and 3 A out, an input range of 4.5 V to 40 V, an oscillator of 127 kHz minimum, 150 kHz typical and 173 kHz maximum, and standby current of 80 µA typical and 200 µA maximum. The selection point is the classic four-external-component 5 V buck for 12 V and 24 V industrial rails, sourced from a domestic maker with its own datasheet and its own guaranteed limits. Selection advice: LM2596-named parts from TI, onsemi, UMW and HGSEMI share a designation, not a datasheet — the UMW adjustable code and the TI /NOPB codes in this catalog carry different electrical tables, so qualify the HGSEMI code against the HGSEMI document, and state the (HG) suffix explicitly so a same-name offer from another maker is not substituted silently. Parameters verified against the HGSEMI LM2596/LM2596HV datasheet (ordering information and electrical characteristics, V1.3).
