(1)

Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical

Characteristics. Specifications do not apply when operating the device outside of its rated operating conditions.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

ESD is tested using the human body model which is a 100pF capacitor discharged through a 1.5k resistor into each pin.

(4)

At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink values (if a

heatsink is used). The junction-to-ambient thermal resistance (

temperature to exceed specified limits, the device will go into thermal shutdown.

(5)

If used in a dual-supply system where the regulator load is returned to a negative supply, the output pin must be diode clamped to

ground.
