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.
