The q denotes specifications which apply over the operating temperature
range.
Note 1: Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2: Unless otherwide specified, testing done at V_CC = 5V
(LT1118-2.5, LT1118-2.85) or V_CC = 7V (LT1118-5). V_EN = V_CC. Output
C_LOAD = 1µF, I_LOAD = 0.
Note 3: All operating conditions include the combined effects of load
current, input voltage and temperature over each parameter’s full range.
Note 4: Load and line regulation are tested at a constant junction
temperature by low duty cycle pulse testing.
Note 5: Dropout voltage is defined as the minimum input to output voltage
measured while sourcing the specified current.
