1 If IP is greater than 50 V, do not pull IOUT less than −0.3 V.

2 If IP is greater than 50 V and IOUT is pulled to less than −0.3 V, connect a

Schottky diode between IOUT and ground. Tie the Schottky cathode to IOUT

and the anode to ground.

Stresses at or above those listed under Absolute Maximum Ratings

may cause permanent damage to the product. This is a stress

rating only; functional operation of the product at these or any other

conditions above those indicated in the operational section of this

specification is not implied. Operation beyond the maximum operat-

ing conditions for extended periods may affect product reliability.

THERMAL RESISTANCE

Thermal performance is directly linked to PCB design and operat-

ing environment. Careful attention to the PCB thermal design is

required.

θJA is the natural convection junction-to-ambient thermal resistance

measured in a one cubic foot sealed enclosure. θJCT and θJCB are

the junction-to-case thermal resistances, top and bottom, respec-

tively.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Charged devi-

ces and circuit boards can discharge without detection. Although

this product features patented or proprietary protection circuitry,

damage may occur on devices subjected to high energy ESD.

Therefore, proper ESD precautions should be taken to avoid

performance degradation or loss of functionality.
