(1) Vilimit is the voltage at which current limit begins to occur, as seen across Rcl (see block diagram) as measured by the UV detection oc-
curing.
(2) Foldback current limit prevents excessive power dissipation in the pass element under short circuit conditions. The ratio is the current
flowing at current limit when the pass element under short circuit conditions. The ratio is the current flowing at current limit when the pass
element is delivering full voltage (when UV first occurs), over the current in the pass element when the output is shorted to ground.
(3) DC and AC transient requirements may be mixed, as long as the total deviation from 3.3V does not exceed Dvreg as specified under the
critical specifications in section 6 of this specification.
