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 20mA, 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.
