Note 1:
The output may be shorted to NEGOUT or GND if the package power dissipation is not exceeded. Typical short-circuit
current from 4V to GND is 40mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(Figures 2a and 2c, 2.5V ≤ V IN ≤ 10V, V OUT = -2V, GND = 0V, R L = ∞ , SHDN = V IN , T A = T MIN to T MAX , unless otherwise noted.
Typical values are measured at V IN = 3.6V and T A = +25°C.)
