integrated circuit r dc components co., ltd. technical specifications of 3-terminal negative voltage regulator description these regulators empoly internal current limiting and thermal shutdown, 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 voltage regulators 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 = ground 2 = input 3 = output da79l12DA79L12A to-92 dimensions in inches and (millimeters) .022(0.56).014(0.36) .050 (1.27) .148(3.76).132(3.36) typ .190(4.83).170(4.33) .100 (2.54) typ .050 (1.27) typ .022(0.56).014(0.36) .190(4.83).170(4.33) .500 (12.70) min 2o typ 5o typ. 2o typ 3 2 1 5o typ. characteristic symbol rating unit input voltage vi -35 v total power dissipation pd internal limit w operating temperature range topr -30 to +75 oc maximum junction temperature tj 125 oc storage temperature range tstg -40 to +125 oc absolute maximum ratings (ta=25oc) characteristic symbol min typ max unit test conditions output voltage DA79L12A vo -11.64 -12.00 -12.36 v tj=25oc da79l12 -11.40 -12.00 -12.60 line regulation regline - - 250 mv tj=25oc, -14.5v vin -27v load regulation regload - - 100 mv tj=25oc, 1ma io 100ma input bias current iib - - 6.0 ma tj=25oc output noise voltage vn - 210 - mv ta=25oc, 10hz f 100khz ripple rejection rr 37 64 - db -15v vin -25v, f=190hz electrical characteristics( vin =-19v, iout=40ma, 0oc tj 125oc, cin=0.33m f, cout=0.1m f, unless otherwise specified)
