This should probably read LM136A/LM236A. The LM136 has an operating
temperature range from -55°C to +150°C, the LM236 from -25°C to
+85°C.

The LM336 is specified at (2.49 +/- 0.10)V at 25°C, and the LM336B at
(2.49 +/- 0.05)V, which is twice as good. Between the two, there is no
difference in temperature stability. The stability of the LM136 and the

LM236 is worse because it refers to a larger temperature range.
