Switch Input. Drain of the internal high-voltage back-to-back p-channel
MOSFETs connected to GON.
Reference Output. Connect a 0.22µF capacitor from REF to GND. REF remains
on in shutdown.
Operational-Amplifier Noninverting Input
Linear-Regulator Supply Input
Operational-Amplifier Inverting Input
IC Supply Input. Bypass IN to GND with a 0.1µF capacitor.
Linear-Regulator Output. OUTL is internally pulled to GND by a 1kΩ resistor in
shutdown. For the MAX8711/MAX8712, OUTL is also the supply input for the
charge-pump regulators.
Supply Input for the Charge-Pump Regulators. Connect a 0.1µF capacitor from
SUPCP to GND.
Negative Charge-Pump Driver Output. Output high level is V
low level is GND. DRVN is internally pulled high to SUPCP when the negative
charge pump is disabled.
Positive Charge-Pump Driver Output. Output high level is V
low level is GND. DRVP is internally pulled low in shutdown.
No Connection. Not internally connected.
Ground
Operational-Amplifier Output. OUTB is internally pulled to GND by a 1kΩ resistor
in shutdown.

Positive Charge-Pump Feedback Input. Connect FBP to the center of a resistive
voltage-divider between the positive charge-pump regulator output and GND to
set the regulator output voltage. Place the divider within 5mm of FBP. FBP is
internally pulled to GND by a 10Ω resistor in shutdown.
