L1188

UNISONIC TECHNOLOGIES CO., LTD L1188 800mA CMOS LDO „ DESCRIPTION Preliminary CMOS IC As UTC LDO, the features of the UTC L1188 include low quiescent current and very low dropout voltage. In order prevent form the bad operating conditions, there are internal thermal shutdown and current fold-back. For stably operation, the UTC L1188 should be connected to an output capacitance of 2.2μF or larger. The UTC L1188 can be an ideal for battery applications, such as portable electronics, wireless devices, cordless phones, PC peripherals and battery powered widgets. 1 „ FEATURES SOT-223 * Extra Low Dropout Voltage * Output Current: 800mA (Guaranteed) * Output Voltage Accuracy:±1.5% * Quiescent Current: 30μA * Internal Over-Temperature Shutdown * With Current limiting * Internal Short Circuit Current Fold-Back * Pre-set Output Voltages In Factory * Very Low Temperature Coefficient „ ORDERING INFORMATION Ordering Number Package 1 G Pin Assignment 2 3 O I Packing Tape Reel L1188G-xx-AA3-A-R SOT-223 Note: Pin Assignment: G:GND O:VOUT I:VIN xx: Output Voltage, refer to Marking Information. www.DataSheet4U.com www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-324.c L1188 „ MARKING INFORMATION PACKAGE VOLTAGE CODE Preliminary CMOS IC MARKING SOT-223 28 :2.8V 33:3.3V „ PIN CONFIGURATION „ PIN DESCRIPTION PIN NO. 1 2 3 PIN NAME GND VOUT VIN DESCRIPTION Ground.
