Note 3: Unless otherwise specified, the LM136-5.0 is specified from −55˚C

≤TA≤+125˚C, the LM236-5.0 from −25˚C≤TA≤+85˚C and the LM336-5.0 from

0˚C

≤TA≤+70˚C.

Note 4: Temperature stability for the LM336 and LM236 family is guaranteed by design. Design limits are guaranteed (but not 100% percent production tested) over

the indicated temperature and supply voltage ranges. These limits are not used to calculate outgoing quality levels. Stability is defined as the maximum charge in

VREF from 25˚C to TA(min) or TA(max).
