Value is specified by design, not subject to production test.
Value is based on the minimum value of the 10 pcs/3 lots samples.
External current-limit accuracy is only applicable to overload conditions greater than 1.5× the current-limit setting.
External current-limit setting is recommended to be higher than 500 mA.
