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