Electrical specifications do not apply when operating the device beyond its specified operating conditions. Note 2:For elevated temperature operation, Tjmax is: LM136 150˚C LM236 125˚C LM336 100˚C Thermal Resistance TO-92 TO-46 SO-8 θja(Junction to Ambient) 180˚C/W (0.4" leads) 440˚C/W 165˚C/W 170˚C/W (0.125" lead) θja(Junction to Case) n/a 80˚C/W n/a Note 3:Unless otherwise specified, the LM136-2.5 is specified from −55˚C≤ TA ≤ +125˚C, the LM236-2.5 from −25˚C≤ TA ≤ +85˚C and the LM336-2.5 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% production tested) over the in- dicated temperature and supply voltage ranges. These limits are not used to calculate outgoing quality levels. Stability is defined as the maximum change in Vreffrom 25˚C to TA (min) or TA (max). www.national.com3
