Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 2: Refer to RETS185H-2.5 for military specifications. Note 3: For elevated temperature operation, TJ MAX is: LM185 150˚C LM285 125˚C LM385 100˚C Thermal Resistance TO-92 TO-46 SO-8 SOT-23 θ ja (Junction to Ambient) 180˚C/W (0.4" Leads) 440˚C/W 165˚C/W 283˚C/W 170˚C/W (0.125" Leads) θ jc (Junction to Case) N/A 80˚C/W N/A N/A www.national.com 4 |
