5A LOW DROPOUT LINEAR REGULATOR  
AZ1084  
General Description  
Features  
The AZ1084 is a series of low dropout positive voltage  
regulators with a maximum dropout of 1.5V at 5A of  
load current.  
·
·
·
·
·
Low Dropout Voltage: 1.3V Typical at 5A  
Current Limiting and Thermal Protection  
Output Current: 5A  
Current Limit: 6.5A  
The series features on-chip thermal limiting which pro-  
vides protection against any combination of overload  
and ambient temperatures that would create excessive  
junction temperatures. It also includes a trimmed band-  
gap reference and a current limiting circuit.  
Operating Junction Temperature Range: 0 to  
o
125 C  
·
·
Line Regulation (Adj Version): 0.015% (Typical)  
Load Regulation (Adj Version): 0.1% (Typical)  
The AZ1084 is available in 1.5V, 1.8V, 2.5V, 2.85V,  
3.3V and 5.0V versions. The fixed versions integrate  
the adjust resistors. It is also available in an adjustable  
version which can set the output voltage with two  
external resistors.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the  
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond  
those indicated under"Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum  
Ratings" for extended periods may affect device reliability.  
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical  
specifications do not apply when operating the device outside of its operating ratings. The maximum allowable  
power dissipation is a function of the maximum junction temperature, T
