Note 1: Dropout voltage is defined as V IN - V OUT , when V OUT is 100mV below the value of V OUT measured when V IN = V OUT(NOM)
+ 0.5V. Since the minimum input voltage is 2.5V, this specification is only meaningful when V OUT(NOM) ≥ 2.5V. For V OUT(NOM)
between 2.5V and 3.5V, use the following equations: Typical Dropout = -93mV/V ? V OUT(NOM) + 445mV; Guaranteed Maximum
Dropout = -137mV/V ? V OUT(NOM) + 704mV. For V OUT(NOM) ≥ 3.5V: Typical Dropout = 120mV; Guaranteed Maximum Dropout
= 225mV.
Note 2: Specifications to -40°C are guaranteed by design, not production tested.
