(1) Unless otherwise specified, the LM136-2.5-N is specified from −55°C ≤ T
A
≤ +125°C, the LM236-2.5-N from −25°C ≤ T
A
≤ +85°C and
the LM336-2.5-N from 0°C ≤ T
A
≤ +70°C.
(2) Temperature stability for the LM336 and LM236 family is specified by design. Design limits are ensured (but not 100% 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 change in V
