(1) The current consumption of the SVS module is not included in the I_CC current consumption data.
(2) t_settle is the settling time that the comparator o/p needs to have a stable level after VLD is switched VLD ≉ 0 to a different VLD value
somewhere between 2 and 15. The overdrive is assumed to be > 50 mV.
(3) The recommended operating voltage range is limited to 3.6 V.
