Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 3:
All typicals are given at V

Note 4:
A higher value output capacitor can be used but the “turn-on” and
“turn-off” time will increase proportionally.
