L11810

UNISONIC TECHNOLOGIES CO., LTD L11810 Preliminary CMOS IC 1A CMOS LOW DROPOUT VOLTAGE „ DESCRIPTION As UTC LDO, the features of the UTC L11810 include low quiescent current and very low dropout voltage. In order to prevent from the bad operating conditions, there are internal thermal shutdown and current fold-back. For stably operation, the UTC L11810 should be connected to an output capacitance of 2.2μF or larger. The UTC L11810 is 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: 1A (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 * Halogen Free „ ORDERING INFORMATION G I Pin Assignment O I G O Packing Tape Reel Tape Reel Ordering Number Package L11810G-xx-AA3-A-R SOT-223 L11810G-xx-AA3-D-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-R502-329.c L11810 „ Preliminary CMOS IC MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING SOT-223 28 :2.8V 33 :3.3V „ PIN CONFIGURATION „ PIN DESCRIPTION PIN NO 1 2 3 PIN NAME VIN GND VOUT DESCRIPTION Input voltage pin whi...
