VO = 3.3 to 9 V 30 VI DC Input voltage VO = 12 to 15 V 35 V VO = 18 to 24 V 40 IO Output current 100 mA PD Power dissipation Internally limited (1) mW TSTG Storage temperature range -65 to 150 °C for L78LxxAC / L78LxxC 0 to 125 TOP Operating junction temperature range °C for L78LxxAB -40 to 125
Notes:
(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.
