Note:
(1) Guaranteed by design.
(2) Regulation is measured at constant junction temperature, using pulsed ON time.
(3) Current Limit is measured at constant junction temperature, using pulsed ON time.
(4) Dropout is measured at constant junction temperature, using pulsed ON time, and the criterion is VOUT inside
target value ± 2%.
(5) Dropout test is skipped at the condition of VIN < 3V.
