ADP3605

–3–

REV. A

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 ADP3605 features proprietary ESD protection circuitry, permanent damage may

occur on devices subjected to high energy electrostatic discharges larger than 600 V HBM.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss

of functionality.

Positive Terminal for the Pump

Capacitor.

Device Ground.

36

Negative Terminal for the Pump

Capacitor.

SD

Logic Level Shutdown Pin. Apply a

down the device. In shutdown mode,

the charge pump is turned off and

quiescent current is reduced to 2

µA

(typical). Apply a logic low or con-

nect to ground for normal operation.

58

Output Voltage Sense Line. This is

used to improve load regulation by

eliminating IR drop on the high

current carrying output traces. For

more detail.

NC

No Connection.

710

Regulated Negative Output Voltage.

Connect a low ESR, 4.7

µF or larger

capacitor between this pin and de-

vice GND.

811

Positive Supply Input Voltage. Con-

nect a low ESR bypass capacitor

between this pin and device ground

to minimize supply transients.
