Q: What do I do with VINLDO1/2 if the pin is not used?
A: If VINDLO1/2 is not used, connect the recommended 2.2 uF capacitor from VINLDO1/2 to GND and connect VINLDO1/2 to SYS. Do not leave this pin floating and do not connect directly to GND.
The output of an LDO can be left open if the LDO is not used.
