5.3 Power-down
5.3.1 Recommended power-down sequence
In the recommended power-down sequence, VPA ramps down before AVDD18 in order
for the RF PA to turn the logic off (depends on the control logic generated from AVDD18).
Also, when the PMIC VBAT is removed, the PMIC cannot guarantee a ramp-down
requirement.
Figure 9 shows the recommended (but not required) power-down sequence.
VPA (2.2V)
AVDD18 (1.8V)
