Do power, low power consumption circuit diagram is as follows:


Circuit in 1117 is the XC6206

Phenomenon:
First not welding XC6206 measured TPS5430 output voltage is 5.3 V, welding XC6206P332 don't weld C25 C26 capacitance output is 4.2 V, welding C25, C26 after normal output is 3.3 V, but at the moment, and then measuring TPS5430 output voltage is 9.2 V, at a loss, because I also need the 5.3 V voltage, now turned into 9.2 V,
