Description

CP+

Positive Terminal for the Pump Capacitor.

GND

Device Ground.

CP−

Negative Terminal for the Pump Capacitor.

Logic Level Shutdown Pin. Apply logic high or connect to VIN 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.

VSENSE

Output Voltage Sense Line. Connect a resistor between this pin and VOUT to set the desired output voltage.

No Connect. Do not connect to this pin.

VOUT

Regulated Negative Output Voltage. Connect a low ESR, 4.7 µF or larger, capacitor between this pin and the

device ground.

VIN

Positive Supply Input Voltage. Connect a low ESR bypass capacitor between this pin and the device ground to

minimize supply transients.

CP+ 1

GND

CP– 3
