Through the Output Power Supply interface, the MC509 module can supply 2.6V and
1.8V power externally with an output current of 20mA (typical value) for external level

If the MC509 module is in Sleep mode, the Output Power Supply interface is in the
low power consumption state (< 500μA). If the MC509 module is in Power Down
mode, the Output Power Supply is in the disabled state.
