UNISONIC TECHNOLOGIES CO., LTDL1119 CMOS IC1.5A LOW DROPOUT REGULATORSDESCRIPTIONThe UTC L1119 is a fast ultra low-dropout linear regulator that developed in CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the device to operate under extremely low dropout conditions.The UTC L1119 allows to operate from a 2.5V~7.0V input supply. Wide range of preset output voltage options are available and respond very fast to step changes in load which makes them suitable for low voltage microprocessor applications.FEATURES* Low ground current* Load regulation of 0.04%* Output current of 1.5A DC is guaranteed * Accurate output voltage.(± 1.5%)* Extremely low output capacitor requirements * Over temperature/ Over current protection*Pb-free plating product number: L1119L-xxORDERING INFORMATIONOrder Number Pin AssignmentNormal Lead Free Plating Package 1 2 3PackingL1119-xx-AA3-A-R L1119L-xx-AA3-A-R SOT-223 G O I Tape Reel L1119-xx-AA3-C-R L1119L-xx-AA3-C-R SOT-223 G I O Tape Reel L1119-xx-AB3-A-R L1119L-xx-AB3-A-R SOT-89 G O I Tape Reel L1119-xx-AB3-B-R L1119L-xx-AB3-B-R SOT-89 O G I Tape Reel L1119-xx-AB3-C-R L1119L-xx-AB3-C-R SOT-89 G I O Tape Reel L1119-xx-AB3-D-R L1119L-xx-AB3-D-R SOT-89 I G O Tape Reel L1119-xx-TN3-D-R L1119L-xx-TN3-D-R TO-252 I G O Tape Reel L1119-xx-TN3-D-T L1119L-xx-TN3-D-T TO-252 I G O TubeMARKING INFORMATIONBLOCK DIAGRAMGNDABSOLUTE MAXIMUM RATINGSPARAMETER SYMBOL RATINGSUNIT Input Supply Voltage V IN-0.3 ~ +7.5 VOutput Voltage V OUT-0.3 ~ +7.5 VOutput Current I OUT Short Circuit ProtectedPower Dissipation P D InternallyLimitedOperating Junction Temperature T OPR-40 ~ +125Storage Temperature T STG-65 ~ +150Note Absolute maximum ratings are those values beyond which the device could be permanently damaged.Absolute maximum ratings are stress ratings only and functional device operation is not implied.RECOMMENDED OPERATING RATINGSPARAMETER SYMBOL RATINGSUNIT Input Supply Voltage V IN 2.5 ~ 7.0 VMaximum Operating Current (DC) I OPR(MAX) 1.5 A Operating Junction Temperature T J-40 ~ +125Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.Absolute maximum ratings are stress ratings only and functional device operation is not implied.ELECTRICAL CHARACTERISTICS(T J=25°C, V IN =V OUT+1V, I L=10mA, C OUT=33µF,unless otherwise specified.)PARAMETER SYMBOL TESTCONDITIONSMINTYPMAX UNITI L = 150 mA 38 45Dropout Voltage (Note) V DI L = 1.5 A 870mVPeak Output Current I PEAK 2.0 2.5 AI L = 150 mA 4 9Ground Pin Current I GNDI L = 1.5 A 5 14mAOutput Voltage Tolerance V OUT 10 mA ≤ I L≤ 1.5AV OUT +1 ≤ V IN≤ 7.0V-1.5 0 +1.5 %Line Regulation ∆V OUT V OUT+1V<V IN<7.0V 0.1 % Load Regulation ∆V OUT10 mA < I L < 1.5 A 1.5 % SHORT CIRCUIT PROTECTIONShort Circuit Current I SC 4.5 A AC PARAMETERSOutput Noise Density ρN(l/f) f = 120Hz 0.8 µVBW = 10Hz – 100kHz 150Output Noise Voltage eNBW = 300Hz – 300kHz 100µV(rms)V IN = V OUT + 1.5VC OUT =100uF, V OUT = 3.3V 60Ripple Rejection RRV IN = V OUT + 0.3VC OUT =100uF, V OUT = 3.3V 40dBOVER TEMPERATURE PROTECTIONShutdown Threshold T SHDN165 °C Thermal Shutdown Hysteresis T HYS 10 °C Note: Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. Dropout voltage specification applies only to output voltages of 2.5V and above. For output voltages below 2.5V, the drop-out voltage is nothing but the input to output differential, since the minimum input voltage is 2.5V.TYPICAL CHARACTERISTICS(V IN =V OUT +1V, V OUT =2.5V, C OUT =33µF, I OUT =10mA, C IN =68µF, Ta =25°C.)-40-200204060801001201400.050.10.150.20.25Temperature (℃)D r o p -O u t (V )Drop-Out Voltage vs Temperature (I L )-40-200204060801001201400.150.1750.20.225Temperature (℃)D r o p -O u t (V )Drop-Out Voltage vs Temperature (V OUT )0.125V OUT vs Temperature0.00D e l t a V O U T (%)-0.10-0.20-0.30-0.40-0.50-0.60-0.70-0.80-0.90-75-50-25255075100125Temperature (℃)100.01010Frequency (Hz)N o i s e ( V / H z )Noise Density1.0000.10010010001000001000003V IN (V)V O U T (V )Input Voltage vs Output Voltage2.50.51.5211234TYPICAL CHARACTERISTICS(Cont.)100Frequency (Hz)Output Noise Density100010000100000100Output Noise Density100010000100000Frequency (Hz)10-1090Frequency (Hz)Ripple Rejection vs Frequency1M100K10K1K1001020304050607080R i p p l e R e j e c t i o n (d B )Load Transient Response20 I O U T (A)VO U T (V )Line Transient Response10 s/DIV V I N (V )V O U T (V )Line Transient Response10 s/DIVV I N (V )V O U T (V )TYPICAL CHARACTERISTICS(Cont.)Line Transient Response10s/DIVV I N (V )V O U T (V )Line Transient Response10 3.253.33.35V I N (V )V O U T (V ) 5.34.33.453.4。
