Note 1. Exceeding the absolute maximum rating may damage the device.
Note 2. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Note 3. The device is not guaranteed to function outside its operating rating.
Note 4. Off is VEN≦0.8Vand on is VEN≧2.4V for the AP1201X-H. Off is VEN≧2.4V and on is VEN≦0.8V for the AP1201X-L. The enable
input has approximately 200mV of hysteresis. See control threshold charts.
