Note 2: Guaranteed by design for TA = -40°C.
Note 3: Guaranteed for a junction temperature (TJ) equal to the operating temperature range. E-grade parts are guaranteed by
design to operate up to TJ = +125°C. For TJ above +125°C, specifications exceed the operating limits.
Note 4: Dropout voltage is (VIN_ - VOUT_) when VOUT_ falls to 100mV below its nominal value at VIN_ = (VOUT_ + 1V). For example,
the MAX8862 is tested by measuring the VOUT_ at (VIN_ = 5.95V for the MAX8862L, VIN_ = 4.175V for the MAX8862T, and
VIN_ = 3.85V for the MAX8862R) then VIN_ is lowered until VOUT_ falls 100mV below the measured value.
