Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
All operating conditions include the combined effects of load may cause permanent damage to the device. Exposure to any Absolute current, input voltage and temperature over each parameter’s full range. Maximum Rating condition for extended periods may affect device
Note 4:
Load and line regulation are tested at a constant junction reliability and lifetime. temperature by low duty cycle pulse testing.
Note 2:
Unless otherwide specifi ed, testing done at VCC = 5V
Note 5:
Dropout voltage is defi ned as the minimum input to output voltage (LT1118-2.5, LT1118-2.85) or VCC = 7V (LT1118-5). VEN = VCC. measured while sourcing the specifi ed current. Output CLOAD = 1μF, ILOAD = 0. 1118fd 3
