3.3.5 Output Power Supply Interface

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