Note 2: Unless otherwise noted, these specifications apply: −50˚F
≤ Tj ≤ + 300˚F for the LM34 and LM34A; −40˚F ≤ Tj ≤ +230˚F for the LM34C and LM34CA; and
+32˚F
≤ Tj ≤ + 212˚F for the LM34D. VS = +5 Vdc and ILOAD = 50 µA in the circuit of Figure 2; +6 Vdc for LM34 and LM34A for 230˚F ≤ Tj ≤ 300˚F. These specifications
also apply from +5˚F to TMAX in the circuit of Figure 1.
Note 3: Thermal resistance of the TO-46 package is 720˚F/W junction to ambient and 43˚F/W junction to case. Thermal resistance of the TO-92 package is 324˚F/W
junction to ambient. Thermal resistance of the small outline molded package is 400˚F/W junction to ambient. For additional thermal resistance information see table
in the Typical Applications section.
Note 4: Regulation is measured at constant junction temperature using pulse testing with a low duty cycle. Changes in output due to heating effects can be computed
by multiplying the internal dissipation by the thermal resistance.
Note 5: Tested limits are guaranteed and 100% tested in production.
Note 6: Design limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage ranges. These limits are not used to cal-
culate outgoing quality levels.
Note 7: Specification in BOLDFACE TYPE apply over the full rated temperature range.
