Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The absolute maximum supply voltage rating of 16V is for
unregulated circuits using LT1054. For regulation mode circuits using
LT1054 with V
increased to 20V. The absolute maximum supply voltage for LT1054L is 7V.
Note 3: The devices are guaranteed by design to be functional up to the
absolute maximum junction temperature.
Note 4: For voltage loss tests, the device is connected as a voltage inverter,
with pins 1, 6, and 7 (3, 12, and 13 S package) unconnected. The voltage
losses may be higher in other configurations.

portion of the curve. The incremental slope of the curve will be higher at
currents <10mA due to the characteristics of the switch transistors.
Note 6: All regulation specifications are for a device connected as a
positive-to-negative converter/regulator with R1 = 20k, R2 = 102.5k,

Note 7: The S8 package uses a different die than the H, J8, N8 and S
packages. The S8 device will meet all the existing data sheet parameters.
