(2) All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (3) The junction temperature (TJ in °C) is calculated from the ambient temperature (TA in °C) and power dissipation (PD in watts) as follows: TJ = TA + (PD × RθJA ) where RθJA (in °C/W) is the package thermal impedance provided in the Thermal Information section. 6 Submit Documentation Feedback Copyright © 2009–2014, Texas Instruments Incorporated Product Folder Links: LM25011 LM25011-Q1 LM25011A LM25011A-Q1 |
