† The recommended operating voltage range is limited to 3.6 V.

‡ tsettle 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.

NOTES:

1. The current consumption of the SVS module is not included in the ICC current consumption data.

2. The SVS is not active at power up.
