Note 1: For inputs >12V, add a 1 kΩ 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.
