There are many vendor makes the 78M05 at different price, what makes them different? Here is what I have found:
2. The Closest Competitor: Diodes, AS78L05RTR-E1, 24 active transistors:
4.The third closest competitor: ST L78M05ABDT-TR, 17 Transistors 5.Other competitors uses 15 or less transistors: UTC, 78D05AL, 78D05LL, 78D05L, 15 transistors,

The number of active transistors determined the size of the silicon die, which affects the cost heavily. The rule of thumb is: 80% of the quality control/issues can be determined by design. |

This is another comment on: how important it is for quality control: "就单说纹波方面,TI出的比国产的2596都要低很多的,只可惜实在是太贵了。 |

>原来是这个原因,不知道应该怎么区分呢,谢谢! I think the following three factors have a lot of affects: First, it is the silicon design; Secondly, the silicon manufacturing process. Thirdly, packages process for IC. |
