(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 in a dual-supply system, the output must be diode clamped to GND.
(4) Maximum power dissipation is a function of T
J
(max), θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P

JA
. Operating at the absolute maximum T
J
of 150°C can affect reliability.
(5) The package thermal impedance is calculated in accordance with JESD 51-7.
