Help identify IC - SD1021
« on: November 23, 2018, 10:40:50 pm »
I bought a cheap 12v USB car adaptor on eBay to use in a bench powersupply project, and found this IC inside.
I know it must be a 5v regulator but can not find the datasheet for it.
The numbers on it is:    1741     and    SD1021.
I traced the circuit and it looks like this.

Can anybody tell me more about this IC, what is it's max. current that it can deliver?

1741 = manufactured week 41 of 2017.
No need to search the internet for that number.
