L1119-50-TN3-O-R

UNISONIC TECHNOLOGIES CO., LTD L1119 1.5A LOW DROPOUT REGULATORS 1 1 CMOS IC 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. SOT-223 TO-252 1 SOT-89 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-xx ORDERING INFORMATION Order Number Normal Lead Free Plating L1119-xx-AA3-A-R L1119L-xx-AA3-A-R L1119-xx-AA3-C-R L1119L-xx-AA3-C-R L1119-xx-AB3-A-R L1119L-xx-AB3-A-R L1119-xx-AB3-B-R L1119L-xx-AB3-B-R L1119-xx-AB3-C-R L1119L-xx-AB3-C-R L1119-xx-AB3-D-R L1119L-xx-AB3-D-R L1119-xx-TN3-D-R L1119L-xx-TN3-D-R L1119-xx-TN3-D-T L1119L-xx-TN3-D-T Note: Pin assignment: I: VIN O: VOUT G:GND L1119L-xx-AA3-A-R (1)Packing Type (2)Pin Assignment (3)Package Type (4)Output Voltage Code (5)Lead Plating Package SOT-223 SOT-223 SOT-89 SOT-89 SOT-89 SOT-89 TO-252 TO-252 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 Packing Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tube (1) R: Tape Reel, T: Tube (2) refer to Pin Assignment (3) AA3: SOT-223, AB3: SOT-89, TN3: TO-252 (4) xx: refer to Marking Information (5) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 7 QW-R502-051,B L1119 MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING CMOS IC L1119 SOT-223 VOLTAGE CODE LEAD PLATING PIN CODE DATE CODE 1 12 15 18 25 33 50 :1.2V :1.5V :1.8V :2.5V :3.3V :5.0V 2 3 PIN CODE DATE CODE VOLTAGE CODE SOT-89 L1119 1 2 3 LEAD PLATING TO-252 U TC L1119 VOLTAGE CODE LEAD PLATING PIN CODE DATE CODE 1 2 3 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 7 QW-R502-051,B L1119 BLOCK DIAGRAM CMOS IC VIN VOUT - + GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 7 QW-R502-051,B L1119 ABSOLUTE MAXIMUM RATINGS CMOS IC PARAMETER SYMBOL RATINGS UNIT Input Supply Voltage VIN -0.3 ~ +7.5 V Output Voltage VOUT -0.3 ~ +7.5 V Output Current IOUT Short Circuit Protected Power Dissipation PD Internally Limited ℃ Operating Junction Temperature TOPR -40 ~ +125 Storage Temperature TSTG -65 ~ +150 ℃ Note Absolute maximum ratings are those values beyond which the device could be permanently damaged.
