Note 1:
The dropout voltage is defined as V

_ - V
OUT
_, when V
OUT
_ is 100mV below the set output voltage (the value of V
OUT
_ for
V
IN
_ = V
OUT
_ + 500mV). Since the minimum input voltage range is 2.5V, this specification is only meaningful when the set
output voltage exceeds 2.7V (V
OUT_(NOM)
≥
2.7V).
Note 2:
Specifications to -40

C are guaranteed by design, not production tested.
