1 / 6 page UNISONIC TECHNOLOGIES CO., LTD LR1107/E CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2012 Unisonic Technologies Co., Ltd QW-R102-033.H 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 Package Pin Assignment Packing Lead Free Halogen Free 1 2 3 4 5 LR1107L-xx-AA3-A-R LR1107G -xx-AA3-A-R SOT-223 G O I - - Tape Reel LR1107L-xx-AE3-3-R LR1107G -xx-AE3-3-R SOT-23 O G I - - Tape Reel LR1107L-xx-AB3-C-R LR1107G -xx-AB3-C-R SOT-89 G I O - - Tape Reel LR1107L-xx-AB3-D-R LR1107G -xx-AB3-D-R SOT-89 I G O - - Tape Reel LR1107L-xx-AF5-R LR1107G-xx-AF5-R SOT-25 I G SD S O Tape Reel LR1107EL-xx-AF5-R LR1107EG-xx-AF5-R SOT-25 I G SD E O Tape Reel Note: Pin Assignment: I:VIN O:VOUT G:GND SD: SD E: ERROR S:SET/ADJ |
