*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: V_IN = V_OUT + 1V, I_L = 0.1mA, C_L = 3.3µF, SHDN > V_IH, T_A = 25°C, unless other-
wise specified. BOLDFACE type specifications apply for junction temperatures of
– 40°C to +125°C.
