UZ1084-XX-TA3-T

UNISONIC TECHNOLOGIES CO., LTD UZ1084 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. 1 LINEAR INTEGRATED CIRCUIT 1 TO-220 TO-220F 1 TO-252 FEATURES *Fast transient response *Low dropout Voltage at up to 5A *Load regulation : 0.5% typical *On-chip thermal limiting 1 TO-263-3 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 1 TO-263 Lead-free: UZ1084L-xx Halogen-free: UZ1084G-xx ORDERING INFORMATION Ordering Number Pin Assignment Package Normal Lead Free Halogen Free 1 2 3 UZ1084-xx-TA3-T UZ1084L-xx-TA3-T UZ1084G-xx-TA3-T TO-220 A/G O I UZ1084-xx-TF3-T UZ1084L-xx-TF3-T UZ1084G-xx-TF3-T TO-220F A/G O I UZ1084-xx-TN3-R UZ1084L-xx-TN3-R UZ1084G-xx-TN3-R TO-252 A/G O I UZ1084-xx-TQ2-R UZ1084L-xx-TQ2-R UZ1084G-xx-TQ2-R TO-263 A/G O I UZ1084-xx-TQ2-T UZ1084L-xx-TQ2-T UZ1084G-xx-TQ2-T TO-263 A/G O I UZ1084-xx-TQ3-R UZ1084L-xx-TQ3-R UZ1084G-xx-TQ3-R TO-263-3 A/G O I UZ1084-xx-TQ3-T UZ1084L-xx-TQ3-T UZ1084G-xx-TQ3-T TO-263-3 A/G O I Note: 1. xx: Output voltage, refer to Marking Information. 2.
