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.

Typical values are at T A = T J = +25 C.)

Limits over the operating temperature range are guaranteed by design. Note 2: Resistors were added from to to aid with the power dissipation during testing. Note 3: Dropout is measured as follows: Connect a resistor from to. Connect R SSE =.56Ω from to. Set V = V +3V (record V as V 1 ). Reduce V until V =.97 x V 1 (record as V 2 and V 2 ). ΔV DO = V 2 - V 2. Note 4: I = ma. Note 5: t ON time includes the delay and the rise time needed for I to reach 9% of its final value. t OFF time is the time needed for I to drop below 1%. See the Typical Operating Characteristics. t ON and t OFF are tested with 13Ω from to. Note 6: Thermal shutdown does not function if the output of the 5V reference is shorted to ground. Shorting to disables the output. (V = 12V, V = V, C =.1μF, I =, =, R SSE =.56Ω, connect to, V = 4V, T A = +25 C, unless otherwise noted.)
