Quectel Mini PCIe Board Power Supply Circuit


Hi everyone,i am designing power supply for Quectel mini PCIe modules,and trying to avoid voltage drops :unamused:

I uploaded two screenshots,one of them from module design guide and another one from mini pcie design guide.two different output voltages VBAT= 3.8V and 3v3 by same adjust resistors on the same voltage regulator.I want to use for 3.3V but i am confused about this.

Can i use this adjust resistors 100k / 47k and get 3v3 ?

Thank you.

No, :you can use this adjust resistors 82k / 47k and get 3v3 .You can refer to the following figure
