is specified for the worst-case conditions with the device soldered on a
circuit board.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

+ Positive Terminal for the Pump Capacitor.
2 GND Device Ground.
3 C
P
− Negative Terminal for the Pump Capacitor.
4 SD Logic Level Shutdown Pin. Apply logic high or connect to V
IN
to shut down the device. In shutdown mode, the
charge pump is turned off, and the quiescent current is reduced to 2 µA (typical). Apply a logic low or connect to
ground for normal operation.
5 V
SENSE
Output Voltage Sense Line. Connect a resistor between this pin and V
OUT
to set the desired output voltage.
6 NC No Connect. Do not connect to this pin.
7 V
OUT
Regulated Negative Output Voltage. Connect a low ESR, 4.7 µF or larger, capacitor between this pin and the
device ground.
8 V
IN
Positive Supply Input Voltage. Connect a low ESR bypass capacitor between this pin and the device ground to
minimize supply transients.
