(1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which
the device is intended to be functional, but does not specity performance limits. For specifications and test conditions, see Electrical
Characteristics. The specifications apply only for the test conditions listed. Some performance characteristics may degrade when the
device is not operated under the listed test conditions.
(2) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
(3) At elevated temperatures, devices must be derated based on package thermal resistance. The devices in TO-220 package must be
derated at θ_jA = 50°C/W (with 0.5in², 1oz. copper area), junction-to-ambient (with no heat sink). The devices in the DDPAK/TO-263
surface-mount package must be derated at θ_jA = 60°C/W (with 0.5in², 1oz. copper area), junction-to-ambient. The SOT-223 package
must be derated at θ_jA = 90°C/W (with 0.5in², 1oz. copper area), junction-to-ambient.
(4) If used in a dual-supply system where the regulator load is returned to a negative supply, the output must be diode-clamped to ground.
(5) The output PMOS structure contains a diode between the V_IN and V_OUT terminals. This diode is normally reverse biased. This diode will
get forward biased if the voltage at the output terminal is forced to be higher than the voltage at the input terminal. This diode can
typically withstand 200mA of DC current and 1Amp of peak current.
