UNISONIC TECHNOLOGIES CO., LTD UZ1084 LINEAR INTEGRATED CIRCUIT 5A ADJUSTABLE/FIXED LOW DROPOUT LINEAR REGULATOR  DESCRIPTION The UTC UZ1084-ADJ/Fixed voltages are low dropout three-terminal regulators with 5A output current capability. These devices have been optimized for low voltage applications including VTT bus termination, where transient response and minimum input voltage are critical. On-chip thermal limiting provides protection against any combination of overload and ambient temperature that would create excessive junction temperatures.  FEATURES *Fast transient response *Low dropout Voltage at up to 5A *Load regulation : 0.5% typical *On-chip thermal limiting  APPLICATIONS *Desktop PCs, RISC and embedded processors’ supply *GTI, SSTL logic reference bus supply *Low voltage VCC logic supply *Battery-powered circuitry *Post regulator for switching supply *Cable and ADSL modems’ DSP core supply *Set Top Boxes and Web Boxes modules’ supply www.unisonic.com.tw Copyright © 2021 Unisonic Technologies Co., Ltd 1 of 6 QW-R102-010.P UZ1084  LINEAR INTEGRATED CIRCUIT ORDERING INFORMATION Ordering Number Pin Assignment Package Lead Free Halogen Free 1 2 3 UZ1084L-xx-TA3-T UZ1084G-xx-TA3-T TO-220 A/G O I UZ1084L-xx-TF3-T UZ1084G-xx-TF3-T TO-220F A/G O I UZ1084L-xx-TN3-R UZ1084G-xx-TN3-R TO-252 A/G O I UZ1084L-xx-TNA-R UZ1084G-xx-TNA-R TO-252-3 A/G O I UZ1084L-xx-TQ2-T UZ1084G-xx-TQ2-T TO-263 A/G O I UZ1084L-xx-TQ2-R UZ1084G-xx-TQ2-R TO-263 A/G O I UZ1084L-xx-TQ3-T UZ1084G-xx-TQ3-T TO-263-3 A/G O I UZ1084L-xx-TQ3-R UZ1084G-xx-TQ3-R TO-263-3 A/G O I Notes: 1. xx: Output voltage, refer to Marking Information. 2.
