Full range is 0°C to 70°C for the C-suffix and −40°C to 125°C for the I-suffix. If not specified, full range is −40°C to 125°C.
‡
Disable time and enable time are defined as the interval between application of the logic signal to SHDN
and the point at which the supply current
has reached half its final value.
