Attention :
This is a LDO Regulators module,Must be noted when using:

1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
4 If the input and output voltage difference is too large, please use it in small current output situations.
5 If it overheats, add a heat sink
