NOTES
1
Capacitors C
, C
and C
P
in the test circuit are 4.7
μ
F with 0.1
ESR. Capacitors with higher ESR may reduce output voltage and efficiency.
2
See Figure 1 conditions.
3
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
4
For the adjustable version, a 1% resistor should be used to maintain output voltage tolerance. For both device types, tolerances can be improved by >1% using larger
value and lower ESR capacitors for C
O
and C
P
.

This is a stress rating only, operation beyond these limits can cause the device to be
permanently damaged.

is specified for worst case conditions with device soldered on a circuit board.
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 ADP3607 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.
WARNING!
