UZ2085

UNISONIC TECHNOLOGIES CO., LTD UZ2085 Preliminary LINEAR INTEGRATED CIRCUIT 3A ADJUSTABLE/FIXED LOW DROPOUT LINEAR REGULATOR DESCRIPTION The UTC UZ2085-xx series are low dropout three-terminal regulators with 3A output current capability. These devices have been optimized for low voltage applications including VTT bus termination in which transient response and minimum input voltage are critical. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limitation provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. 1 TO-252 FEATURES * Fast transient response * Low dropout voltage at up to 3A * Load regulation: 0.05% typical * Trimmed current limit * On-chip thermal limiting * Ultra low current consumption (0.35mA typ.) * Ultra low Adjustment Current (7μA typ.) * Ultra low minimum Load (0.3mA typ.) * Support MLCC ORDERING INFORMATION Ordering Number Pin Assignment Package Lead Free Halogen Free 1 2 3 UZ2085L-xx-TN3-R UZ2085G-xx-TN3-R TO-252 A/G O I Note: 1. xx: Output Voltage, refer to Marking Information. 2.
