† The recommended operating voltage range is limited to 3.6 V.
‡ tsettle is the settling time that the comparator output must 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.
§ The current consumption of the SVS module is not included in the ICC current consumption data.
