Negative Voltage Output Pin
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the VSS2 pin. Non polarity capacitors
can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0μF capacitor that should have the low ESR (Equivalent

the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
