Note 2:
Guaranteed by design for T

= -40°C.
Note 3:
Guaranteed for a junction temperature (T
J
) equal to the operating temperature range. E-grade parts are guaranteed by
design to operate up to T
J
= +125°C. For T
J
above +125°C, specifications exceed the operating limits.
Note 4:
Dropout voltage is (V
IN
_ - V
OUT
_) when V
OUT
_ falls to 100mV below its nominal value at V
IN
_ = (V
OUT
_ + 1V). For example,
the MAX8862 is tested by measuring the V
OUT
_ at (V
IN_
= 5.95V for the MAX8862L, V
IN_
= 4.175V for the MAX8862T, and
V
IN_
= 3.85V for the MAX8862R) then V
IN_
is lowered until V
OUT_
falls 100mV below the measured value.
