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?
