RIPPLE
The
G
denotes specifications which apply over the specified
temperature range.
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. All typicals are given at T
A
= 25
°
C.

Note 3:
C-grade device specifications are guaranteed over the 0

°
C
temperature range. In addition, C-grade device specifications are assured
over the –40
°
C to 85
°
C temperature range by design or correlation, but
are not production tested.
