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

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
