integrated circuit r dc components co., ltd. technical specifications of 3-terminal positive 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 = output 2 = ground 3 = input DA78L09DA78L09a 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 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 DA78L09a 8.73 9.00 9.27 tj=25oc DA78L09 8.55 9.00 9.45 output voltage DA78L09a vo 8.55 - 9.45 v 1ma io 70ma DA78L09 8.50 - 9.50 DA78L09a 8.55 - 9.45 1ma io 40ma and DA78L09 8.50 - 9.50 11.5v vin 24v line regulation regline - - 200 mv tj=25o c, 11.5v vin 24v - - 150 tj=25oc, 13v vin 24v load regulation regload - - 45 mv tj=25oc, 1ma io 40ma - - 90 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 11.5v vin 24v output noise voltage vn - 70 - mv ta=25oc, 10hz f 100khz ripple rejection rr 38 44 - db 15v vin 25v, f=120hz dropout voltage vd - 1.7 - v tj=25oc electrical characteristics( vin =15v, iout=40ma, 0oc tj 125oc, cin=0.33m f, cout=0.1m f, unless otherwise specified)
