Note 3

Note 1:

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.

2:

Switching times are ensured by design.

3:

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

cuit, otherwise, pin 3 must be left floating.
