integrated circuit r dc components co., ltd. technical specifications of low current positive voltage regulator 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 dm78l12DM78L12A characteristic symbol rating unit input voltage vi 35 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) 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 characteristic symbol min typ max unit test conditions DM78L12A 11.64 12.00 12.36 tj=25oc output voltage dm78l12 vo 11.40 12.00 12.60 v 11.40 12.00 12.60 1ma io 70ma 11.40 12.00 12.60 1ma io 40ma, 14.5v vin 27v line regulation regline - - 250 mv tj=25oc, 14.5v vin 27v - - 200 tj=25oc, 16v vin 27v load regulation regload - - 50 mv tj=25oc, 1ma io 40ma - - 100 tj=25oc, 1ma io 100ma input bias current iib - - 6.0 ma tj=25oc input bias current change diib - - 0.1 ma 1ma io 40ma - - 1.5 16v vin 27v output noise voltage vn - 80 - mv ta=25oc, 10hz f 100khz ripple rejection rr 40 54 - db 15v vin 25v, f=120hz dropout voltage vd - 1.7 - v tj=25oc peak output current imax - 140 - ma tj=25oc electrical characteristics( vin =19v, iout=40ma, 0oc tj 125oc, cin=0.33m f, cout=0.1m f, unless otherwise specified)
