UNISONIC TECHNOLOGIES CO., LTD L11830 CMOS IC www.unisonic.com.tw 1 of 6 Copyright © 2011 Unisonic Technologies Co., Ltd QW-R502-536.a 3A LOW DROPOUT LINEAR REGULATOR „ DESCRIPTION The UTC L11830 belonged to low quiescent current, low dropout, linear regulators operated fr om 2.25V to 6V input and are guaranteed to deliver 3A. Wide range of preset output voltage options are available. Built-in low on-resistance transistor provides low dropout voltage and large output current. The UTC L11830 is designed and optimized for battery-powered systems to work with low noise. The UTC L11830 consumes less than 2μA in shutdown mode. Other features include ultra low dropout voltage, current limiting protection, thermal shutdown protection and high ripple rejection ratio. „ FEATURES * 3A Guaranteed Output Current * low quiescent current: 60μA (typ.) * 2μA Shutdown Current * Short Circuit Current Fold-back * Low Temperature Coefficient * Current Limiting Protection * Thermal Shutdown Protection * Excellent Line/Load Transient * SENSE Option Improves Load Regulation „ ORDERING INFORMATION Note: Pin Assignment: I:VIN O:V OUT G:GND S: SHDN A: SENSE Ordering Number Pin Assignment Lead Free Halogen Free Package 1234 5 Packing L11830L-xx-TQ2-D-R L11830G-xx-TQ2-D-R TO-263 I G O - - Tape Reel L11830L-xx-TQ2-D-T L11830G-xx-TQ2-D-T TO-263 I G O - - Tube L11830L-xx-TQ3-A-R L11830G-xx-TQ3-A-R TO-263 G O I - - Tape Reel L11830L-xx-TQ3-A-T L11830G-xx-TQ3-A-T TO-263 G O I - - Tube L11830L-xx-TQ5-R L11830G-xx-TQ5-R TO-263-5 I S G A O Tape Reel L11830L-xx-TQ5-T L11830G-xx-TQ5-T TO-263-5 I S G A O Tube
