(1)
To be in regulation, minimum VIN1 (or VIN2) must be greater than VOUT1,NOM (or VOUT2,NOM) by an amount determined by external
components. Minimum VIN3 = VOUT3 + VDO or 2.2 V, whichever is greater.
(2)
Maximum VOUT is dependent on external components and will be less than VIN. Parameter is not production tested.
(3)
Depends on external components.
