3A LOW DROPOUT LINEAR REGULATOR  
AZ1085  
General Description  
Features  
The AZ1085 is a series of low dropout positive voltage  
regulators with a maximum dropout of 1.5V at 3A of  
load current.  
·
·
·
·
·
·
·
Low Dropout Voltage: Typical 1.3V at 3A  
Current Limiting and Thermal Protection  
Output Current: 3A  
Current Limit: 4.5A  
The series features on-chip thermal shutdown. It also  
includes a bandgap reference and a current limiting cir-  
cuit.  
o
Operating Junction Temperature: 0 to 125 C  
Line Regulation: 0.015% (Typical)  
Load Regulation: 0.1% (Typical)  
The AZ1085 is available in 1.5V, 1.8V, 2.5V, 2.85V,  
3.3V, 5.0V and adjustable versions. The fixed versions Applications  
integrate the adjust resistors. The adjustable version  
can set the output voltage with two external resistors.
