Notes:
1/ The brown-out threshold voltage is the Vdd voltage at which the regulator will be disabled and
Regout will be pulled to Vss.
2/ In normal operation, the regulator will provide high-side current of up to 50mA, but current
sinking capability is typically under 1uA. The overvoltage clamp is intended to limit the voltage at
Regout when it is pulled up by an external source.
3/ The limits shown are 100% tested at 25C only. Test limits are guard-banded based on
temperature characterization to guarantee compliance at temperature extremes.
