LR1107G-33-AA3-A-R

UNISONIC TECHNOLOGIES CO., LTD LR1107/E CMOS IC 600mA FAST ULTRA LOW DROPOUT LINEAR REGULATOR  DESCRIPTION The UTC LR1107/E operate from a +2.5V ~ +7.0V input supply as fast ultra low-dropout linear regulators. Wide output voltage range options are available. The fast response characteristic to make UTC LR1107/E suitable for low voltage microprocessor application. The low quiescent current operation and low dropout quality caused by the CMOS process. The UTC LR1107/E has ultra low dropout voltage; 300mV at 600mA load current typically. The ground pin current is typically 200uA at 1mA load current. SET/ADJ Mode (for LR1107): Connect an external resistive voltage-divider from VOUT to this pin to set the output voltage from 1.145V to 5V. ERROR Flag (for LR1107E): When the output voltage drops 10% below nominal value Error flag goes low. Output Voltage Precision: Multiple output voltage options are available and ranging from 1.2V ~ 5.0V at room temperature with a guaranteed accuracy of ±1.5%, and ±3.0% when varying line, load and temperature.  FEATURES * Ultra Low Dropout Voltage * Low Ground Pin Current * 0.68% Load Regulation * The Guaranteed Output Current is 600mA DC * Output Voltage Accuracy ± 1.5%  * ERROR Flag Indicates Output Status * VOUT can be Adjusted From 1.145V to 5V. * Low Output Capacitor Required * Overtemperature Protection and Overcurrent Protection ORDERING INFORMATION Ordering Number Lead Free Halogen Free LR1107L-xx-AA3-A-R LR1107G-xx-AA3-A-R LR1107L-xx-AE3-3-R LR1107G-xx-AE3-3-R LR1107L-xx-AB3-B-R LR1107G-xx-AB3-B-R LR1107L-xx-AB3-C-R LR1107G-xx-AB3-C-R LR1107L-xx-AB3-D-R LR1107G-xx-AB3-D-R LR1107L-xx-AF5-R LR1107G-xx-AF5-R LR1107EL-xx-AF5-R LR1107EG-xx-AF5-R Note: Pin Assignment: I:VIN O:VOUT G:GND SD: SD www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd Package SOT-223 SOT-23 SOT-89 SOT-89 SOT-89 SOT-25 SOT-25 1 G O O G I I I Pin Assignment 2 3 4 O I G I G I I O G O G S SD G E SD 5 O O Packing Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel E: ERROR S：SET/ADJ 1 of 6 QW-R102-033.L LR1107/E  CMOS IC MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING SOT-223 L: Lead Free G: Halogen Free Date Code LR1107 Pin Code Voltage Code 1 2 3 18:1.8V 25:2.5V 28:2.8V 2J:2.85V 33:3.3V 50: 5.0V SOT-23 SOT-89 SOT-25 (LR1107E) 18:1.8V 25:2.5V 28:2.8V 2J:2.85V 33:3.3V 50: 5.0V AD: ADJ SOT-25 (LR1107)  PIN CONFIGURATION VOUT 5 ERROR 4 1 2 3 VIN GND SD SOT-25 (for LR1107E)  VOUT 5 SET/ADJ 4 1 2 3 VIN GND SD SOT-25 (for LR1107) SOT-23 PIN DESCRIPTION PIN NAME VIN GND I/O SD I ERROR (for LR1107E) SET/ADJ (for LR1107) VOUT DESCRIPTION Input supply Ground O O O Shutdown LR1107/E enable; when the SD pin connects to GND will shutdown the LR1107/E; At normal operation, SD must be tied to VDD through a 10KΩ pull up resistor.
