Note:
1 In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA
2 V- cannot be used alone, or no voltage output.But you can just use V
3 The startup current of the module is 2.5-3 times the operating current.
4 Increasing the 1UF-10UF MLCC capacitor reduces the startup current
