Note 3 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.
