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.
Lead-free:
Halogen-free: UZ1084G-xx
UZ1084L-xx
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
