UNISONIC TECHNOLOGIES CO., LTD L1119 Preliminary CMOS IC 1.5A LOW DROPOUT REGULATORS DESCRIPTION The 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 ORDERING INFORMATION Ordering Number Lead Free Halogen Free L1119L-xx-AA3-A-R L1119G-xx-AA3-A-R L1119L-xx-AA3-C-R L1119G-xx-AA3-C-R L1119L-xx-AB3-A-R L1119G-xx-AB3-A-R L1119L-xx-AB3-B-R L1119G-xx-AB3-B-R L1119L-xx-AB3-C-R L1119G-xx-AB3-C-R L1119L-xx-AB3-D-R L1119G-xx-AB3-D-R L1119L-xx-TN3-D-R L1119G-xx-TN3-D-R L1119L-xx-TN3-D-T L1119G-xx-TN3-D-T L1119L-xx-TQ2-D-R L1119G-xx-TQ2-D-R L1119L-xx-TQ2-D-T L1119G-xx-TQ2-D-T Note: Pin assignment: I: VIN O: VOUT G: GND www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package SOT-223 SOT-223 SOT-89 SOT-89 SOT-89 SOT-89 TO-252 TO-252 TO-263 TO-263 Pin Assignment 1 2 3 G O I G I O G O I O G I G I O I G O I G O I G O I G O I G O Packing Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tube Tape Reel Tube 1 of 4 QW-R502-051,Da L1119 Preliminary CMOS IC MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING L: Lead Free G: Halogen Free L1119 Pin Code SOT-223 Date Code Voltage Code 1 SOT-89 12 15 18 25 33 50 :1.2V :1.5V :1.8V :2.5V :3.3V :5.0V TO-252 TO-263 Pin Code Voltage Code Date Code L1119 1 2 L: Lead Free G: Halogen Free 3 UTC L1119 Pin Code L: Lead Free G: Halogen Free LOT Code Voltage Code Date Code 1 3 2 2 3 BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R502-051,Da L1119 Preliminary CMOS IC ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS Input Supply Voltage VIN -0.3 ~ +7.5 Output Voltage VOUT -0.3 ~ +7.5 Output Current IOUT Short Circuit Protected Power Dissipation PD Internally Limited Operating Junction Temperature TJ -40 ~ +125 Storage Temperature TSTG -65 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.

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.
