Through the VCC_EXT1 and VCC_EXT2 interfaces, the MU509-65 module can
supply 1.8 V and 2.6 V power externally with an output current of 20 mA (typical value)
for external level conversion or other applications.
If the MU509-65 module is in sleep mode, the output power supply interface is in
the low power consumption state (< 500
μA).
If the MU509-65 module is in power down mode, the output power supply is in the
disabled state.
