The first path is the junction to the case (JC) which is defined by the package style, and the second path is case to ambient (CA) thermal resistance which is dependent on board layout. The final operating junction temperature for any set of conditions can be estimated by the following thermal equation: TJUNC = TAMB + PD (JC) + PD (CA) = TAMB + PD (JA) The CM3014 uses a SOT23-5 package. When this package is mounted on a double-sided printed circuit board with two square inches of copper allocated for "heat spreading", the resulting JA is 175C/W. Based on a maximum power dissipation of 320mW (Load x Vin-Vout = 150mA x 2.2V) with an ambient of 70C the resulting junction temperature will be: GROUND CURRENT [uA] Output Voltage Change vs. Temperature (1mA Load) 50 40 OUTPUT CHANGE [mV] 30 20 10 0 -10 -20 -30 -40 -50 -50 -25 0 25 50 75 100 125 TEMPERATURE [oC] Ground Current vs. Temperature 100 80 60 40 20 0 0 25 50 75 100 o TJUNC = TAMB + PD (JA) = 70C + 315mW (175C/W) = 70C + 57.75C = 127.75C 7KHUPDO FKDUDFWHULVWLFV ZHUH PHDVXUHG XVLQJ D GRXEOH VLGHG ERDUG ZLWK WZR VTXDUH LQFKHV RI FRSSHU DUHD FRQQHFWHG WR WKH *1' SLQV IRU KHDW VSUHDGLQJ Measurements showing performance up to a junction temperature of 125C were performed under light load conditions (1mA). 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 the CM3014 with an overall JA of 175C/W, which allows up to 450mW to be dissipated safely. 3OHDVH FRQVXOW &$0' 7HFKQLFDO 6XSSRUW IRU DVVLVWDQFH ZLWK WKHUPDO DQDO\VLV RI WKH &0 ZLWK UHVSHFW WR D VSHFLILF DSSOLFDWLRQ 125 JUNCTION TEMPERATURE [ C] )LJXUH &0 3HUIRUPDQFH YV 7HPSHUDWXUH 2002 California Micro Devices Corp.
