These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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 specify performance limits. For ensured specifications and test conditions, see
Electrical Characteristics. The ensured 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) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
(4) 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 0.5in
2
, 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 0.5in
2
, 1oz. copper area), junction-to-ambient. See Application Hints.
(5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP396X output must be diode-clamped to
ground.
(6) 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.
