† All characteristics are measured with a 10-µF capacitor across the input and a 10-µF capacitor across the output. Pulse testing techniques are

used to maintain the junction temperature as close to the ambient temperature as possible.

‡ Current limit test specified under recommended operating conditions

NOTE 2: Dropout is defined as the input-to-output differential at which VOUT drops 100 mV below the value of VOUT, measured at

VIN = VOUT(nom) + 1.5 V.
