Recommended Operating Conditions are conditions under which operation of the device is intended to be functional, but does not
guarantee specific performance limits.
(2)
Minimum VIN operating voltage is always 4.5 V. The minimum input power supply voltage can be 3.0 V after start-up, assuming VIN
voltage is supplied from an available external source.
