Notes:
1.Vout=1.204*(1+R1/R2)=3.296V;
R1=52.3K,R2=30.1K are recommended for better performance.
2.RT9043GB from RichTek for second source.
MicroSD:
When ESP32 resets,we use GPIO13(default high when reset
and after reset) to control all slave LDO to LOW.In this case ,
all slave device should keep in default-steady status.
