integrated circuit r dc components co., ltd. description these regulators empoly internal current limiting and thermalshutdown, making them essentially indestructible. they can deliver up to 100ma output current, if the case temperature can keep in t c=25oc. they are intended as fixed voltageregulators in a wide range of applications including local(on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. in addition, they can be used with power pass elements to make high-current voltage regulators. pinning 1 = output2 = ground 3 = input dm78l08DM78L08A characteristic symbol rating unit input voltage vi 30 v total power dissipation pd internal limit w operating temperature range topr 0 to +125 oc maximum junction temperature tj 125 oc storage temperature range tstg -55 to +150 oc lead temperature(soldering 10 sec.) tl 260 oc absolute maximum ratings (ta=25oc) characteristic symbol min typ max unit test conditions DM78L08A 7.76 8.00 8.24 tj=25oc dm78l08 7.70 8.00 8.30 output voltage DM78L08A vo 7.76 8.00 8.24 v 1ma io 70ma dm78l08 7.60 8.00 8.40 DM78L08A 7.76 8.00 8.24 1ma io 40ma and dm78l08 7.60 8.00 8.40 10.5v vin 23v line regulation regline - - 175 mv tj=25oc, 10.5v vin 23v - - 125 tj=25o c, 11v vin 23v load regulation regload - - 40 mv tj=25oc, 1ma io 40ma - - 80 tj=25oc, 1ma io 100ma input bias current iib - 2.0 5.5 ma tj=25oc input bias current change diib - - 0.1 ma 1ma io 40ma - - 1.5 11v vin 23v output noise voltage vn - 60 - mv ta=25oc, 10hz f 100khz ripple rejection rr 39 45 - db 11v vin 21v, f=120hz dropout voltage vd - 1.7 - v tj=25oc peak output current imax - 140 - ma tj=25oc electrical characteristics( vin=14 v, iout=40ma, 0oc tj 125oc, cin=0.33m f, cout=0.1m f, unless otherwise specified) sot-89 dimensions in inches and (millimeters) .063(1.60).055(1.40) .066(1.70).059(1.50) .167(4.25).159(4.05) .016(0.41).014(0.35) .120(3.04) .117(2.96) .181(4.60).173(4.40) .060(1.52).058(1.48) .020(0.51).014(0.36) .102(2.60).095(2.40) 1 2 3 technical specifications of low current positive voltage regulator
