Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All current into device pins are positive; all current out of device
pins are negative; all voltages are referenced to ground unless otherwise
specified.

Note 3: An internal Zener at the GATE pin clamps the charge pump voltage
to a typical maximum operating voltage of 26V. External voltage applied to
the GATE pin beyond the internal Zener voltage may damage the part. If a
lower GATE pin voltage is desired, use an external Zener diode. The GATE
capacitance must be < 0.15 F at maximum V
