9 Power Supply Recommendations

Apply a supply voltage of 2.7 V to 5.8 V to the VIN pin. In case the 3.3-V linear regulator is supposed to be used, a higher minimum voltage needs to be applied, allowing for some drop-out. As in most cases, the 3.3-V rail needs to come up before the main boost-converter does, an RC-element on the EN pin can delay the ramp of the boost converter.
