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 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.
