*Stresses above 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 above
those indicated in the operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for extended periods
may affect device reliability.
ELECTRICAL CHARACTERISTICS: VIN = VOUT + 1V, IL = 0.1mA, CL = 3.3µF, SHDN > VIH, TA = 25°C, unless otherwise noted.
BOLDFACE type specifications apply for junction temperatures of – 40°C to
+125°C.
