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 VCC = 5V

(LT1118-2.5, LT1118-2.85) or VCC = 7V (LT1118-5). VEN = VCC. Output

CLOAD = 1µF, ILOAD = 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.
