They were performed under light load conditions (5mA); this allows the ambient temperature to be representative of the internal junction temperature. Note: The use of multi-layer board construction with separate ground and power planes will further enhance the overall thermal performance. In the event of no copper area being dedicated for heat spreading, a multi-layer board construction using only the minimum size pad layout will typically provide a CM3002 device packaged in a SOIC package with an overall JA of 50C/W, which allows up to 0.8W to be dissipated safely. 3OHDVH FRQVXOW &$0' 7HFKQLFDO 6XSSRUW IRU DVVLVWDQFH ZLWK WKHUPDO DQDO\VLV RI WKH &0 IDPLO\ RI UHJXOD WRUV ZLWK UHVSHFW WR D VSHFLILF DSSOLFDWLRQ
