What are the advantages of HK7833 compared to ASM1117-3.3V? Why does the former cost 1 yuan, while the latter only costs 0.1 yuan?

Comparing the two voltage regulators, both are linear regulators, and the AMS1117 can output a maximum current of 1A, while the HK7833 can only output a maximum current of 500ma, but the price is 10 times more expensive.

The latter has many suppliers of the same model, large production capacity, fierce competition, thin profits, and is naturally cheaper. The former is not a public version product, the cost dilution is far lower than the latter, and the sales cost is also high, so it is naturally expensive. But the 10-fold price difference is more related to the channel. The channel markup of the former is much greater than that of the latter, and the difference in ex-factory price is much smaller.

In addition to the previous post, the price given by the original poster is not very reasonable and too extreme. In small quantities, the price of the latter may be high, but it is also high, while the former may have some hidden reasons. In large quantities, there is a price difference between the two, but the price difference is not large.

Hmm. Thank you for your answer and sharing your experience.
