The q denotes specifications which apply over the specified temperature
range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: C grade device specifications are guaranteed over the 0
°C to 70°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.
VIN = 2.7V to 5V, CFLY = 0.22µF, CIN = COUT = 10µF, TMIN to TMAX unless otherwise specified. (Note 2)
