Unless noted the limits at room temperature are guaranteed and 100% production tested. Limits over temperature are guaranteed but not

100% tested.

Note 1: The brown-out threshold voltage is the Vdd voltage at which the regulator will be disabled and VREG (output) will be pulled to Vss.

Note 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, Vcl is intended to limit the voltage at VREG (output) when it is pulled up by an external source.

Note 3: Not 100% production tested but limits are guaranteed by design.
