The STM32WL series is a well-designed SoC chip designed by ST for the Internet of Things, especially for the LPWAN field
I'm going to use the MP2307DN to make a 2A, 5V circuit. I found an old schematic and it's a proven circuit! It works, but when I opened the "datasheet", I found the circuit diagram was like this.

As shown in the picture, when I change the voltage, the current remains unchanged, but when I change the resistance of R2, the current changes. Why is that?
