Ground.
When logic low is applied to this pin,
oscillator is shut down.
On the ADP1109A (Adjustable), this
pin goes directly to the comparator
input. On the ADP1109-3.3,
ADP1109-5 and ADP1109-12, this
pin is connected through the internal
resistor that sets the output voltage.

CAUTION
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.
Although the ADP1109 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
