Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its normal value with V
Devices are ESD sensitive. Handling precautions recommended.

Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle (≤1%). The maximum continuous supply voltage is
26V. Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
