Shutdown, Logic Level Shutdown Pin. Application of a
logic low to this pin will place the regulator in normal
operation. T he device will be put into shutdown mode
with the shutdown pin pulled to V
IN
. In Shutdown
mode the charge pump is turned off. Connect to ground
for normal operation.
V

, Output Voltage Sense Line. T his is used to im-
prove load regulation performance by eliminating IR
drop on the output traces. See application section for
more detail. For normal operation, connect Pin 5 to
V

Output Pin. Regulated negative output voltage.
Connect a low ESR capacitor between this pin and de-

ADP3604–SPECIFICATIONS
WARNING!
ESD SENSITIVE DEVICE
C AUT ION
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 ADP3604 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
