EZ1085  
3 Amp Positive Voltage Regulator  
POWER MANAGEMENT  
Description  
Features  
The EZ1085 series of high performance positive voltage  
regulators are designed for use in applications requiring  
low dropout performance at up to 3A. Additionally, the  
EZ1085 series provides excellent regulation over  
variations in line, load and temperature.  
‹ Low dropout voltage: 1.3V max. for EZ1085C,  
1.4V max. for EZ1085I  
‹ Full current rating over line and temperature  
‹ Fast transient response  
‹ ±2% total output regulation over line, load and  
temperature  
‹ Adjust pin current max 90µA over temperature  
‹ Fixed/adjustable output voltage (EZ1085C)  
‹ Line regulation typically 0.015%  
‹ Load regulation typically 0.05%  
‹ Industrial temperature range (EZ1085I)  
‹ TO-220 and TO-263 packages  
Outstanding features include low dropout performance  
at rated current, fast transient response, internal  
current limiting and thermal shutdown protection of the  
output device.  
A variety of options are available for maximum flexibility:  
the EZ1085C has both fixed and adjustable voltage  
options and is designed for use in commercial applica-  
tions and the EZ1085I is adjustable only for industrial  
applications.  
Applications  
‹ Printer and plotter supplies  
‹ Instrumentation  
‹ Medical equipment  
‹ Microcontroller systems  
‹ Telecommunication systems  
‹ Motherboards  
All devices are available in the popular TO-220 and  
TO-263 packages.  
‹ Switching supply post regulation
