(1) 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 under " recommended operating
conditions " is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The PNP pass transistor has a parasitic diode connected between the input and output. This diode normally is reverse biased
(V
IN
> V
OUT
), but will be forward biased if the output voltage exceeds the input voltage by a diode drop (see Application Information for
more details).
(3) If load is returned to a negative power supply, the output must be diode clamped to GND.
(4) Maximum power dissipation is a function of T

. The maximum allowable power dissipation at any allowable ambient
temperature is P

of 150 ° C can affect reliability.
(5) The package thermal impedance is calculated in accordance with JESD 51-7.
