When the module is in sleep mode, LDO6_1V8 wakes up periodically or randomly. Considering the actual requirement
for power consumption during sleep mode, you can use either LDO6_1V8 or an external LDO for power supply. For lower
power consumption, use an external LDO instead.
LDO5_1V8
111
PO
1.8 V output
Vnom = 1.8 V
I
O
max = 20 mA
Power supply for
external GPIO’s
pull-up and level
shift circuits.
LDO6_1V8
3
125
PO
1.8 V output
Vnom = 1.8 V
I
O
max = 150 mA
Power supply for
sensors, cameras,
and I2C pull-up
circuit.
If it is used, connect
an external
1.0

Vnom = 2.85 V
I
O
max = 150 mA
Reserved power
supply.
If it is used, add a
1.0
–2.2 μF bypass
capacitor.
If it is not used,
keep it open.
LDO17_2V85
129
PO
2.85 V output
Vnom = 2.85 V
I
O
max = 450 mA
Power supply for
AVDD of LCM, TP,
sensors and
cameras.
If it is used, connect
an external
2.2
–4.7 μF
capacitor to this pin
in parallel.
If it is not used,
keep it open.
LDO16_2V8
193
PO
2.8 V output
Vnom = 2.8 V
I
O
max = 55 mA
