–SENSE
Feedback loop connection for remote sensing
output voltage. Must always be connected to
output return for proper operation.
+SENSE
Feedback loop connection for remote sensing
output voltage. Must always be connected to
+VOUT for proper operation.
*Absolute maximum ratings are limiting values, to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure of
absolute maximum rating conditions for extended periods of time may affect
device reliability.

CAUTIO N
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
T herefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.
