Note 4：The dropout voltage is defined as VIN-VOUT, which is measured when VOUT drops 2% of its normal value with the

specified output current.

Note 5：Load regulation and dropout voltage are measured at a constant junction temperature by using a 40ms low duty

cycle current pulse.

Note 6：Guarantee by design.
