ELECTRICAL

CHARACTERISTICS

? Stresses above 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 above those indicated in the

Absolute Maximum Ratings?

Note 3

Note 1:

2:

3:

For inputs >12V, add a 1 k Ω resistor in series with the input. See Section 2.0 “Typical Performance

Curves” for input current graph.

Switching times are ensured by design.

For operation below 7V, pin 3 (LOCK DIS) should be tied to ground to disable the lockout and start-up

circuit, otherwise, pin 3 must be left floating.
