5 / 29 page L78LxxAB - L78LxxAC - L78LxxC Maximum ratings 5/29 3 Maximum ratings Table 2. Absolute maximum ratings Symbol Parameter Value Unit VI DC Input voltage VO= 3.3 to 9 V 30 V VO= 12 to 15 V 35 VO= 18 to 24 V 40 IO Output current 100 mA PD Power dissipation Internally limited (1) 1. Our SO-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate area of copper on the printed circuit board is available for heat-sinking. The external dimensions are the same as for the standard SO-8. mW TSTG Storage temperature range -65 to 150 °C TOP Operating junction temperature range for L78L00AC 0 to 150 °C for L78L00AB -40 to 125 Table 3. Thermal data Symbol Parameter SO-8 TO-92 SOT-89 Unit RthJC Thermal resistance junction-case. (Max) 20 15 °C/W RthJA Thermal resistance junction-ambient. (Max) 55 (1) 200 °C/W 1. Considering 6 cm2 of copper Board heat-sink. |
